Beijing 65438+1October 2 1 News According to the Voice of China News Hyperlink, recently, domestic semiconductor quantum computing has made new progress. Academician Guo Guangcan of the Chinese University of Science and Technology cooperated with American and Australian researchers and the original quantum * * * in China to realize the ultra-fast manipulation of silicon-based spin qubits, and the spin flip rate exceeded 540 MHz-which has been reported internationally. Related research papers have been published in the academic journal Nature Communication.

How does quantum become a computer? How to understand the "silicon-based spin qubit"? How will quantum computers in China develop in the future?

What is quantum? How does quantum become a computer?

Quantum is not a specific physical quantity. 1900, Planck first put forward the concept of quantum. Planck assumes that when light radiation interacts with matter, its energy is not continuous, but one after another, and an "energy" is called quantum. Einstein believed that the energy of light radiation itself is "quantized", and one energy is the smallest unit of light energy.

According to the different laws of physical motion, scientists call the world composed of substances that obey the classical laws of motion "classical world" and the world composed of substances that obey the laws of quantum mechanics "quantum world". "Quantum" is the general term for material objects in the quantum world. It can be microscopic particles such as photons, electrons, atoms, nuclei and elementary particles, or macroscopic quantum systems such as Bose-Einstein condensation, superconductors and Schrodinger cats.
