Quantum computers are expected to overturn the existing ordinary computers with their astonishing computational speed and performance. "Quantum chips", as the "brains" of quantum computers, are the core of the difference between ordinary computers and ordinary computers. At present, research institutions both at home and abroad have begun to conduct research in this field, and China has undoubtedly been at the forefront.
The picture shows the peripheral circuits of quantum chips in Quantum Lab of University of Science and Technology of China. The quantum chip is black.
According to CCTV news reports, the Quantum Lab of China University of Science and Technology has successfully developed semiconductor quantum chips. The successful development of this quantum chip means that quantum computers can implement logic operations and information processing. This semiconductor quantum chip is already in the laboratory. It has been shown, but it is not yet clear what the details of this quantum chip are.
In addition to the computational part, the laboratory's quantum memory has also made new progress, namely solid-state quantum memory. It is understood that the sandwich-type solid-state quantum memory in the figure below can work in an auxiliary device with a magnetic field at a low temperature.
Solid-state quantum memory
Zhou Zongquan, a researcher at the Key Laboratory of Quantum Information at the Chinese Academy of Sciences, said, “A current research direction in the laboratory is to make this quantum memory small and neat, in order to extend its life span. In the end we hope to make a classic portable U disk. Devices that are as easy to use as possible, enabling the transmission of ultra-long-distance quantum state quantum information."
So where is Quantum Computing?
As we all know, quantum is the smallest indivisible energy unit, and one qubit has two states 0 and 1 at the same time. The corresponding N qubits can store 2 Nth power data at the same time. Therefore, the effect of a quantum computer operating once is the same as that of an ordinary electronic computer that performs 2 N-th order operations. In other words, quantum computing can complete the parallel processing of 2 N-th power data at a time. This parallel computing speed can completely kill. Traditional computer.
Guo Guangcan, an academician of the Chinese Academy of Sciences and a professor at the University of Science and Technology of China, stated that "a quantum computer is a disruptive technology. Once it is successfully developed, all passwords can be cracked. In addition, it can also solve big data problems."
Of course, quantum technology is still mainly in the experimental stage and there is still a long way to go before it can be used commercially.
