A number of innovative quantum information technologies were showcased at the 24th China Hi-Tech Fair (CHTF), which took place in Shenzhen, Guangdong province from Nov 15 to 19, 2022.

These include the QR series quantum random number generator is a true random number system based on vacuum fluctuation (701)/phase noise (901) developed by Dingdun Quantum Information Technology Co. It is the fastest commercial quantum random number generator in the world and has applications in the field of practical quantum cryptosystems, which require high-quality randomness and security.

The "Wuyuan" series of superconductive quantum computers, developed by Hefei Origin Quantum Computing Technology Co, is the first engineered quantum computer in China.

The quantum information light source intelligent precision sensing system of Shenzhen Guihe Semiconductor Co is composed of the quantum information light source that is based on the chaotic light quantum information generator and the quantum information chaotic light detection system. The quantum information chaotic light source is a wide spectrum noise-like signal generated by the photoelectric semiconductor device and the SPAD receiving device, which can be widely used in the precision industry and quantum communication.
