UNSW pure silicon quantum computer chip in operation
These include silicon spin qubits, ion traps, superconducting cycles, diamond vacancies, and top-up qubits Unfortunately, in all of the above architectures, qubits are rather fragile and prone to computational errors.
Even quantum processors, which contain only a few qubits, are often too big for mass production. The good news is that researchers from the University of New South Wales (UNSW) have developed solutions that address both A new pain point of the chip design.
Researchers at UNSW have tended to use silicon spin quantum computing because they can reuse existing silicon-based microprocessor technology.
According to a recent paper published in the journal Nature Communications, this is a new type of computing chip designed on the basis of a complementary metal-oxide-semiconductor (CMOS) process.
The silicon quantum processor consists of a huge two-dimensional quantum bit array, using traditional silicon transistors to control the spin of the qubit and two qubits to handle the logic interactions.
Papers, Dr. Menno Veldhorst said:
By selecting one of the electrodes in the qubit, we can control the spin of a qubit, which stores a quantum binary code of '0' or '1', and selecting the electrode between the qubits allows the two quanta Bit on the implementation of logical interaction or operation.
World's first complete design of a silicon quantum computer
The team said that all of the key components required for quantum computing can be implemented in a single chip, and that the architecture of the chip includes error-correction code that relies on multiple qubits that store a single data, Spin qubits design.
To prepare for production, the UNSW team expects to make some necessary changes to the chip design, while on the other hand, they are proud of the speed with which they have achieved their milestones since they created a double-quantum bit logic gate just two years ago, And demonstrated how to do quantum computation on a silicon chip.
