Experts have spoken highly of a significant computing breakthrough achieving quantum computational advantage announced by a Chinese research team on Friday. The team established a quantum computer prototype, named "Jiuzhang," via which up to 76 photons were detected. This achievement marks that China has reached the first milestone on the path to full-scale quantum computing -- a quantum computational advantage, also known as "quantum supremacy," which indicates an overwhelming quantum computational speedup. No traditional computer can perform the same task in a reasonable amount of time, and the speedup is unlikely to be overturned by classical algorithmic or hardware improvements, according to the team.
The Chinese Academy of Sciences and Alibaba announced the establishment of a joint quantum computing laboratory on Thursday in Shanghai with the goal of developing superfast quantum computers. Alibaba will spend $4.8 million for 5 consecutive years to support creation of superfast computers.
A research group led by Academician GUO Guangcan from Key Laboratory of Quantum Information and Synergetic Innovation Center of Quantum Information & Quantum Physics of University of Science and Technology of China (USTC) of Chinese Academy of Sciences made progress in quantum computing based on solid quantum chip. Researchers realized the controlled-Not quantum logic gate in two-charge-qubit system of semiconductor quantum dot. Their study was published on Nature Communications with "Conditional rotation of two strongly coupled semiconductor charge qubits" as its title.
