Google relies on a 72-bit quantum computer to aspire to a quantum hegemonic plan or to be toppled.
On May 8, Kuai Technology learned from Alibaba. The Boomerang Quantum Laboratory has recently developed the world’s most powerful quantum circuit simulator, “Taizhang”, and successfully took the lead in successfully simulating the Google Random Quantum Circuit with 81-bit and 40-layer as the benchmark. Previously, the simulation to reach this layer could only be handled. 49 bits.
Alibaba 'Taizhang' Simulator Comparing with the Results of Main Simulator Simulating Google Random Circuit
As a disruptive technology, quantum computing has always been a hot topic of scientific research. However, the realization of quantum computing is very difficult. At present, the world's quantum computer with public technical parameters is only a few 20 bits. The existence of quantum circuit simulators means to help understanding, designing quantum computer hardware, and exploring quantum algorithms and applications.
For the first time, 'Taizhang' made it possible to verify and test 'moderate-scale' quantum algorithms with 50-200 qubits, thus providing a powerful tool for assisting the design of medium-scale quantum algorithms, quantum software, and even quantum computers.
In March 2018, Google released a plan to develop the world's first high-quality 72-bit quantum computer, and previously proposed a set of random quantum circuits that implement Quantum Hegemony. The result of 'Tai Zhang' broke Google’s desire to Set of plans to achieve the original plan of quantum hegemony.

'Another highlight of Taizhang's is that the communication overhead is minimal, which can be based on the powerful computing power of Alibaba Group's online computing platform to complete simulations that cannot be accomplished by the world’s most powerful supercomputers. In the 64 (8x8) bit 40-layer simulation, 'Tai Zhang' can be completed in 2 minutes and only uses 14% of the computing resources of the Alibaba Computing Platform online cluster.
The Alibaba Dharma Quantum Laboratory was led by a permanent professor at the University of Michigan and led by Shi Quan, a world-renowned quantum scientist.
Earlier this year, Mario Szegedy, a Hungarian-American computer scientist, was the two Gondell Prize winners for theoretical computers. Currently, the laboratories are in a period of rapid growth in talent introduction.
