Set micro-grid Guangzhou coverage
Today, I am proud to announce that with the unremitting efforts of more than 30,000 Samsung colleagues in China, we have successfully established a one-stop business system integrating R&D, design, production, sales and services. Said Samsung China has become a de facto Chinese local enterprise. "Takashima, President of Samsung's Mobile Communications Division, announced the good news from the very beginning of the launch of the Galaxy S9 / S9 + National Bank.
As we all know, the Samsung Galaxy S9/S9+ flagship phone was officially unveiled on the opening day of the MWC 2018 exhibition at the end of February, and attracted many eye-catchers with its stunning design and extremely strong performance. At 7 pm on March 6, Samsung again Officially released in Guangzhou S9 / S9 + version of the national Bank.
First, let's take a brief look at the configuration of the Galaxy S9/S9+. Both the S9 and S9+ are designed with a 'full-view screen' and equipped with a Qualcomm Snapdragon 845 processor. The S9 is equipped with 4GB of memory and provides 64/128GB of storage. Capacity of 3000mAh, S9 + with 6GB of memory, providing 64/128 / 256GB three storage specifications, the battery capacity of 3500mAh.
But in fact, as Mr. Gao Dongzhen said at the press conference, the biggest improvement for the S9 series phones is not in the hardware, but in the soft experience. So, in the end what is the performance? Look!
Shot when coagulation: within a second freeze 960 moments
It can be said, S9 series of mobile phones in the experience of the largest evolution of the number of new camera module it is reported that the Samsung S9 + just DxOMark mobile phone camera review also refresh the world's highest score.
First of all, the Galaxy S9 upgrades the CMOS to a new generation of 'Super Fast' full dual-core sensors, along with a dedicated, dedicated dynamic memory for superior Galaxy-S9 + shooting performance at 960 frames per second Screen, allowing users to shoot ultra-slow-motion video four times slower than regular slow motion, in other words, if the user has taken a 0.2 second instant, the Galaxy S9 can turn it into a super slow motion video of 6 seconds in length Share with your friends.
At the same time, Galaxy S9 / S9 + uses similar to the human eye iris expansion and contraction similar to the principle of F1.5 / F2.4 intelligent variable aperture, the light is too dark or too bright can automatically adjust, making shooting at different times and in different environments Photos are very bright and clear.This intelligent dual-aperture design is also a major highlight of the evolution of smart phone camera.
In addition, the newly added dynamic sprite feature is also very eye-catching, not only allows users to create their own exclusive facial expression camera package, but also can be directly through third-party software for social sharing, bringing more personalized communication.
Safety performance: iris + face unlock combined into one
Samsung S8 has the most smartphone encryption and unlock mode, including the password, graphics, fingerprint recognition, portrait recognition, iris recognition five, easy to use, and high security.Samsung S9 series phones on the basis of this has been optimized, Re-design of the unlock mechanism, the portrait and iris unlocked unlocked into a mix resulting in a hybrid unlock, smart identification, as long as one kind of situation can be unlocked.
It is noteworthy that for some tech savvy people, it is possible to hear that modern Android phones have a 'safe boot' feature that prevents both viruses and malicious code from starting up at boot time. Integrity checks have been shown to be effective in improving cell phone security, but what you may not know is that all Android phones are actually based on the code and technology that Samsung contributed to Google Inc. In Samsung, Cell phone such as the Galaxy S9 series, it actually runs the 'full version' of the technology, the Samsung Knox.
Samsung Knox is a combination of hardware and software encryption system, which is higher than the level of Andrews operating system itself, you can truly privacy of the phone, the system-level hardware-level file encryption, inspection and attack prevention. For example, we may now have Have had such an experience: just chatting with someone chatting with a commodity a minute ago, the next minute to open the mobile shopping APP, it appeared in the recommendation in. This is actually one of the personal privacy disclosure manifestation.
In the Galaxy S9 system with the "security folder", you can put the application, important privacy documents, etc. all under the protection of the Knox encryption mechanism running in this program will not be other third parties Mechanism to monitor, you can truly protect the key data and personal privacy, property safety.
Artificial Intelligence: 'Bixby Vision' Optimized again
AI is a hot topic in the near term. In fact, last year Samsung launched Bixby Chinese. Many operations can be done through Bixby.
With the help of upgraded AI and AR technology, the 'Bixby vision' on the Samsung S9 has also been strengthened: In addition to the previous filming artifacts and camera artifacts, the 'Bixby Vision' is more supportive of the AR mode and can recognize The result is directly superimposed on the viewfinder, such as shopping, real-time translation, etc., which makes people feel Samsung's technical superiority and humanized design as the first large-scale plant of Android.
Currently, Samsung mobile phones have established partnerships with first-tier internet companies such as Tencent, Sina, Netease, Mobi, Ofo, Ali, Baidu, and others. They have jointly developed the former Chinese Bixby AI assistants and integrated them in the Samsung mobile phone products in China. A lot of convenient functions for grounding gas.
Samsung's new game engine will greatly enhance the gaming experience
With the increasing demand for mobile game experience from users, Samsung's new game engine will greatly enhance the game experience. Among them, AI game engine brings higher and more stable game frame rate, and full-scale 3D engine further enhances game running and image processing capabilities. The AR engine is based on ARCore's cooperation and will bring this augmented reality platform to consumers this year.
In addition, Samsung and Tencent have jointly developed the Game SDK Suite to significantly improve game performance and stability. At the same time, it supports a new generation of Vulkan 3D graphics processing capabilities. Taking King Glory as an example, the stability of the frame rate after optimization is significant. Better than the existing market version, less power consumption and less power consumption, while the game quality has also improved.
In addition to cooperation with Tencent, Samsung will also introduce network acceleration features to improve the network and reduce the adverse impact on the game. Whether using 4G or Wi-Fi has a more stable network experience. Taking into account the actual players often encountered problems , In the call-free, game screen, live broadcast and other aspects of optimization are also more intimate and relaxed.
Three celebrity spokespersons escort the Galaxy S9 series
As we all know, Samsung did not have a spokesperson to the scene before the development of the local community. Now Samsung is also starting to adopt the celebrity endorsement model that domestic mobile phone manufacturers like to use. At the press conference, they announced three spokespersons: Jing Boran, Zhu Yawen and Brilliance Yu, the first two are visiting the scene.
During the press conference, Jingbo shared a lot of interesting ways of shooting, such as disassembling the action drama, looking back at the exaggerated expressions on the lines, etc. It is also possible to create a dynamic facial expression and share it with friends The new dynamic cuteness is also his favorite feature.
Zhu Yawen stated that he always pays attention to and is willing to experience and use black technology. After the experience, he praised Bixby for being very convenient and very powerful. At the scene, Zhu Yawen shared many of Bixby's usage scenarios in life, such as setting up work schedule reminders with Bixby, and traveling. Saying that the destination started navigation, etc. everywhere embodies his true love for artificial intelligence. In addition, Zhu Yawen also brought surprises to Bixby's users. When consumers interact with Bixby in the future, May also receive the Bixby voice reply 'Eggs' brought by Zhu Yawen.
Finally, the young music talent Brilliance also wish Galaxy S9 and S9 + sell through the VCR, and revealed that the future will be more exciting cooperation with Samsung.
Of course, the most worthy of consumer concern is the price of the phone: Samsung S9 64GB 64GB 4G / 64GB version priced at 5799 yuan, 128GB priced at 6099 yuan, Samsung S9 + 64GB version of the national price of 6699 yuan, 128GB version of 6999 yuan, 256GB version of 7599 yuan.
It is worth mentioning that the Samsung Galaxy S9/S9+ not only achieved a number of innovations, but also upgraded its exclusive butler service once again. Within six months of listing, it provided a free 6-month discount screen change service. Users can also Choose to pay a small fee and extend it to 12 months to bring more choices. At the same time, 12 months of battery performance detection and optimization, and 50% battery replacement service are still escorting the user's worry-free security.

The Samsung Galaxy S9|S9+ can also be purchased through the trade-off method, using The designated model old machine will participate in the trade-in replacement and will have the opportunity to get the highest value of RMB 600 for the Samsung Points.
2. Cook talks about 'successor' Who is the candidate inside Apple?
Apple held the 2018 annual general meeting of shareholders at the Steve Jobs Theater in the new headquarters of Apple Park earlier this year. In addition to hosting the first shareholders meeting in the new campus, Apple CEO Tim Cook also mentioned for the first time the topic of future successors.
Tim Cook said that how to correctly pass the baton to future successors will be the next important task. Although the reasons for the mention of successors are not mentioned at this time, the list of currently selected candidate successors has not been disclosed. Perhaps considering the circumstances of the death of former CEO Steve Jobs due to illness, Tim Cook thought that it was not a bad thing to plan ahead for successors and do a good job in the company's future business planning.
If Tim Cook chooses to retire at this time, it is suitable to be the candidate list of Apple CEO successors. It may include Jeff Williams, Director of Apple Operations, Eddy Cue, Director of Service Content, Phil Schiller, Director of Product Marketing, Chief Design Officer Jonathan Ive, Hardware Department Director Dan Riccio, and Angela Ahrendts, Apple's CFO Luca Maestri, head of retail, or Craig Federighi, head of the Apple software business, which has been receiving attention in recent years.
Judging from the current managerial responsibilities of various departments of Apple, Jeff Williams, who is responsible for Apple's global supply and management business, will have the most chance to become CEO successor, but he has large-scale enterprise management experience, and has the ability to connect with Apple employees and consumers. Angela Ahrendts also has many opportunities to become successors, and Craig Federighi, who is responsible for the development of operating systems such as Apple iOS, macOS, etc., is also highly prestigious and may also be one of the future CEO candidates.
However, from the perspective of Tim Cook's ability as the CEO of Apple, prior to his tenure as CEO, Tim Cook was actually the chief operating officer of Apple, and he was also the CEO during the absence of former CEO Steve Jobs, and his ability to manage Apple's supply chain was more to Tim. Cook served as Apple's CEO during the period, set an iPhone, iPad product sales far more than Steve Jobs served as CEO of the overall sales.
During his tenure, Tim Cook drastically reduced the apple's main supply chain from the original 100 to 24, while persuading many supply chains to relocate to adjacent areas of the Apple product manufacturing plant and reducing the apple product inventory cycle from the original one month to six. Day, which even reduced the production cycle time of Mac series models from 4 months to 2 months, even more made Apple become a company specializing in product R&D. Because of this, Apple ranked 35th in 2011 from global top 500 brands. Grew to No. 9 last year and became the most profitable company in the world.
This achievement also enabled Tim Cook to successfully exit his own path under former CEO Steve Jobs and implement his own ideas, which in turn allowed Apple to secure about 80% of the profits in the global smart phone market, while also allowing Apple's market value to grow substantially. , And fight with Alphabet for breaking the trillion-dollar market cap.
Because of this achievement, Tim Cook's successors are bound to have considerable leadership skills, and allow Apple to once again surpass the existing scale of development.
Judging from the current situation, Tim Cook should not temporarily remove the CEO position of Apple, but finding the right succession candidate is still an important matter for Tim Cook in the future, and if it is impossible to pick the right candidate from Apple’s existing department head, perhaps Apple will Consider looking outside for a new CEO.

3. Take a 5G ride, smart phone consumption will increase by US$12 billion over the next three years
Set micro-mesh news, Adobe Digital Research Institute, the latest report pointed out that 5G to enhance network transmission speed, the next three years is expected to bring 12 billion US dollars for mobile commerce new revenue.
In the past few years, as the speed of mobile networks has accelerated, the Revenue Per Visit (RPV) gap between desktops and smartphones has continued to shrink. Among them, the RPV of smart phones only had 20% of desktops at the beginning of 2015. Up to 30% at the end of last year.
In terms of network data traffic, the data traffic between desktops and tablets has shrunk simultaneously in the past three years. Smartphones have only increased in number. They have grown cumulatively by 85% since 2015, and desktops have dropped by 17% during the same period. In addition, an interesting finding has been made. Yes, the better the screen resolution of the mobile phone, the higher the amount of mobile orders. The report found that for each additional 10,000 pixels, the amount of orders increased by 1.18 US dollars, which may be due to the high price of high-resolution mobile phones. The user's spending power is also stronger. (Proofreading/Liu Yang)
4.Google releases the world’s first 72-qubit universal quantum computer
Xin Zhiyuan: Google today announced the launch of a 72-qubit universal quantum computer Bristlecone, which achieved a low error rate of 1%, which is equal to the quantum computer with 9 qubits. Google believes that the use of Bristlecone can achieve quantum hegemony. Zhou IBM exposed the internal structure of its 50 quantum-bit quantum prototypes. Google's dazzling performance in terms of quantum bit counts and error rates, and the timing of the 2018 quantum hegemony race ahead of time, and then we will see Microsoft's rumors. Milestone performance.
Today, Julian Kelly, a research scientist at Google Quantum AI Labs, published a statement in the Google Research Bureau. He introduced peer-reviewed Google’s latest 72-bit qubit computers.
"We just started testing," said John's physicist John Martinis. "From what we know now, we are very optimistic." Martinis said that if everything works well, quantum hegemony may be achieved within a few months. .
Kelly said that the goal of Google Quantum AI Lab is to build a quantum computer that can be used to solve real-world problems. Google's strategy is to use systems that are compatible with universal error correction quantum computers to explore recent applications. Enables the quantum processor to run algorithms outside the scope of classical simulations. It requires not only large-scale qubits, but also low error rate guarantees for the processor in readout and logic operations, such as single-bit gates and Two-door
At the annual meeting of the American Physical Society held in Los Angeles, Google demonstrated a new quantum processor, Bristlecone. This gate-based superconducting system aims to study the systematic error rate and scalability of qubit technology, and optimizes it in quantum simulation. And machine learning applications.
Record 72 qubit quantum computers with an error rate of 1% to achieve quantum hegemony
According to Julian Kelly, the latest device follows the physics principle of the linear array technology of the nine qubit quantum computers previously proposed by Google, and the best results shown by the technology are as follows: Low reading error rate (1%), Single qubit gates (0.1%) and most important double qubit gates (0.6%). The device uses the same pattern as 9 qubits for coupling, control, and readout, but expands it to include 72 Square array of qubits.
In the experiment, the researchers chose this size device to demonstrate the quantum hegemony of the future, studied the first-order and second-order error correction using surface coding, and promoted the development of quantum algorithms on the actual hardware.
The ability to quantify a quantum processor is important before a particular application is explored.Google's theory team has developed a benchmarking tool to accomplish this task by applying random quantum circuits to the system Tasks are randomly assigned and the sampling output is examined for distribution by a classical simulation method. For a quantum processor with a small enough operational error, it can surpass the classical supercomputer problem on a clear computer science-related issue Performance, that is, 'quantum hegemony' These random circuits must be large in terms of both the quantum bits and the calculated length and depth.
Although no one can achieve this goal yet, Google researchers calculated that the goal of quantum hegemony can be perfect by using 49 quantum bits, a circuit depth of over 40, and a 2-bit error of less than 0.5% Prove they believe that the quantum processor superior to the supercomputer experiment proved to be the watershed in this area, but also one of the main goals of the future.
Google had hoped to achieve similar performance on nine qubits but had 72 qubits now and pointed out that Bristlecone would be a convincing principle in the future when it comes to building larger quantum computers Proofing that Google also said running a device such as the Bristlecone at a low system error requires a combination of technologies such as software, control electronics and the processor itself, there is a need for careful system engineering in a few rounds of iterations Observations.
At Google Quantum AI Lab, quantum physics can be achieved using Bristlecone, and learning how to build and operate the device at this level can be an exciting challenge as they look forward to sharing the results, which can also help more researchers Conduct experiments in this area.
Google: From 49 to 72, we are not only better than IBM
As we said before, Google has said it is going to build a 49-qubit quantum computer to realize quantum hegemony, claiming that they are the result of their calculation, and why did you jump to the '72 'qubit this time?
It has long been assumed that 50 qubits of quantum computers are 'starting prices' for quantum hegemony. "Shortly after Google dubbed Quantum Hegemony a 49-qubit quantum computer, IBM said that their research Shows that for some specific quantum applications, it may take 56 or more qubits to achieve quantum hegemony.
Not only that, on November 12, 2017, IBM announced the successful development of a 20-qubit quantum computer and successfully built and tested the world's first 50-qubit quantum computing prototype.
Last week, at the IBM Inaugural Index Developer Conference in San Francisco, IBM showed off its 50 qubits of prototypes and the internal structure was also exposed.
However, to realize quantum hegemony, one has to say the quantum simulation mentioned just now. The most powerful supercomputer at the moment can only simulate 46 qubits. It is very challenging to simulate a universal quantum computer on a traditional computer. Frontier research work. In November 2017, Professor Yuan Shengjun from Wuhan University’s School of Physics and Technology, Professor Jinfengping from Germany’s Yulich Supercomputing Center, Professor Kristel Michielsen and Professor Hans De Raedt from the University of Groningen in the Netherlands jointly tackled the problem. A series of general-purpose quantum computer simulations were implemented on the supercomputer Shenwei Taihu in the Supercomputer Wuxi Center of China to achieve 45-qubit simulations. Then, in December 2017, the team made another breakthrough, achieving 46 qubits. Simulation, set a current world record.
Scalability is one of the challenges facing general-purpose quantum computers. From 45 to 46, it seems that only one bit is added, but in computer simulations, each additional qubit needs to double the memory of the computer. For example, simulating a quantum computer with 45 qubits requires at least 0.5 PB (about 0.5x10 ^ 15 bytes) of memory.
So, to simulate a 72-qubit computer, it would take millions of megabytes of RAM (2 ^ 26 (72-46) bytes). We probably will not be able to use that much memory in supercomputers, so if Bristlecone The ability to run common algorithms faster than the most powerful supercomputers so far will be just around the corner.
Occupy 2018 Quantum Hegemony Competition Match Point, Small Commercial Quantum Computers Appear Within 5 Years
In addition to quantum bits, quantum hegemony also requires a low error rate, a quickest but erroneous quantum computer that is not as good as a classic supercomputer.
According to Google, the minimum error rate for a quantum computer must be within 1% and has a scale close to 100. For the moment, at the error rate, Google has achieved this goal on a 72-bit quantum computer, with a single quantum The bit gate is 0.1% and the double quantum bit gate is 0.6%.
When we can achieve error rates of 0.1-1% for tens or even millions of qubits, the quantum computer will start to really solve the real problem efficiently, which can take ten years or more.
But at least Google believes that before we can create large-scale quantum-bit quantum computers, we might first implement small, even commercial quantum computers, or quantum computing commercial applications.
In 2017, the Google Quantum team said in the Nature issue that they are convinced that even in the absence of a theory that can be fully error-corrected, there will still be small-scale devices in five years that are associated with quantum computing, which will also bring investors Short-term returns. "Early quantum computing devices will have commercial applications in quantum simulation, quantum-assisted optimization, and quantum sampling, and faster computational speed has clear commercial advantages from artificial intelligence to financial and medical fields. '
Google hopes their 72-qubit Bristlecone quantum computer not only enables quantum hegemony but also serves as a test fixture for studying quantum bit scalability and error rates, developing applications such as quantum simulation, optimization and machine learning.
At the end of January 2018, the Financial Times released the news. In the next few weeks, Google and Microsoft will respectively announce two milestone breakthroughs in quantum technology.
Now that Google has given out their 72-qubit quantum computer, let's look at Microsoft.
5. After the rapid growth of ushered in the bottleneck 2018 vivo can turn crises into security?
Sina Technology Zhang Jun
It is an extraordinary year for Chinese smartphone makers in 2017. According to IDC data, shipments of smartphones in the global market and in the Chinese market both showed a year-on-year decline this year.
vivo is one of the most affected companies.From the first quarter of 2016 the first time into the top five global smart phone shipments, from the second quarter of 2017 and due to decline in market share was classified to others; and in the Chinese market , Its shipments growth in the third quarter of 2017 and the fourth quarter consecutive year-on-year decline, but fortunately retained the top three Chinese market rankings.
The rise of vivo and OPPO in 2016 has been seen as relying on the depth of the township's intensive offline outlets and crazy celebrity endorsements, once attracted many manufacturers to follow suit.But facing the weak environment and its own growth bottleneck, vivo Also looking for change and transformation.
In the 345 cities and township markets, vivo is adjusting and optimizing the layout and efficiency of its offline outlets, while in tier-1 and tier-2 cities, vivo upgrades its experience centers to enhance its brand image, while at the same time it has always been considered as lacking in technical details Vivo has also begun to increase investment in new screens, 5G, AI and other new technologies.
Bottleneck after high growth
According to IDC data, in the fourth quarter of 2015, vivo shipped 11.8 million units with a year-on-year increase of 33.8%, accounting for 9.4% of China's smartphone market, ranking the fifth place. In the first quarter of 2016, vivo Shipments in China grew at a year-on-year rate of 121.7% YoY, entering the top three in the Chinese market. Also in this quarter, vivo's growth in the global market reached 123.8% and reached the top five in the global market.
The smartphone market in China slowed down significantly by 2017. The first quarter rose 0.8% YoY, down 0.4% YoY in the second quarter, down 1% YoY in the third quarter and down 15.7% YoY in the fourth quarter, In the whole year, it dropped by 4.9%.
In this context, vivo shipments in China and the world in both growth rate dropped sharply in the first two quarters of shipments in China have dropped to 10% growth rate, or even in the third and fourth quarter Year-on-year, while in the global market, its market share began to decline from the first quarter of 2017 and disappeared in the top five in the following quarters.
