Quantum China Weekly – Volume 8 (2021/05/29-2021/06/04)

Quantum China Weekly

This week, in the business sector, the Origin Quantum open source community completed a new revision and went online, and at this stage the community is soliciting feedback suggestions from the public. SpinQ became the vice president of Shenzhen Computer Society, and Turing Quantum recently settled in Shanghai Danshui River Science and Technology Park.

In the direction of scientific research, researchers from the Key Laboratory of Quantum Information of the Chinese Academy of Sciences made important progress in the research of microwave resonant cavity-semiconductor quantum chip coupling in cooperation with Origin Quantum.

The research team of University of Science and Technology of China (USTC) realized for the first time a multi-mode multiplexed quantum relay fundamental link, demonstrating the accelerating effect of multi-mode multiplexed quantum communication and achieving quantum entanglement of two solid-state memories, providing a new implementation scheme for the construction of high rate and large scale quantum networks.

The University of Science and Technology of China (USTC) is recruiting for the Quantum Computing 2021 seminar, which aims to select talented junior undergraduates for early entry into quantum computing research teams to conduct scientific research activities.

The Laboratory of Quantum Computing and Algorithm Theory at the Institute of Computing, Chinese Academy of Sciences is recruiting researchers in the areas of quantum computing physical experiments, quantum computing theory, theoretical computers and machine learning theory and applications.

The 17th National Symposium on Low Temperature Physics opened successfully, where the Sir Martin Wood Prize for Physical Sciences in China was awarded. Researcher Jin Kui from Institute of Physics, Chinese Academy of Sciences, Professor Jiang Ying and Professor Li Yuan from Peking University received the awards.

Origin Quantum Open Source Community Newly Revamped and Launched

Origin Quantum started to establish the Origin Quantum Open Source Community in 2018, which has recently completed a new revamp and gone live. The community aims to generate more quality content and expose practitioners to this quality content through the community for valuable exchanges and a more robust quantum computing product ecosystem. The community is currently soliciting feedback suggestions from the public.

Origin Quantum finished developing Quantum Bayesian Network application and went live on the cloud platform

Quantum Bayesian Network (QBN) is good at handling a part of complex stochastic systems mainly in security systems, and is an important application direction of quantum computing in many industries with physical device networks or virtual security network systems, such as finance and Internet. The application of Quantum Bayesian Network (QBN) has been developed recently to demonstrate the technical support scope and some basic functions of QBN, which is now online to the Quantum of Origin application cloud platform.

SpinQ became the vice chairman of Shenzhen Computer Society

SpinQ and the Shenzhen Computer Society jointly held a seminar and exchange meeting on quantum computing was successfully held. During the event, SpinQ officially became the vice chairman of the Shenzhen Computer Society, SpinQ said it will continue to promote enterprise cooperation in the field of quantum computing industry, academia and research, and build a good ecological environment.

Turing Quantum settled in the core area of Shanghai Science and Technology Park

Turing Quantum recently settled in Shanghai Danshui Riverside Science and Innovation Park, which creates an opportunity for subsequent cooperation between Shanghai Jiao Tong University and Shanghai Minhang District. Turing Quantum’s office in the park will cover the most core R&D functions such as labs and algorithm research teams.

Chinese scientists achieve quantum dominance in sensor field

Chinese researchers at the University of Arizona have experimentally demonstrated the advantages of quantum computing systems over classical computing systems. The experiments show that equipping sensors with quantum entanglement will give them an advantage over classical sensors: the possibility of generating errors can be reduced by a certain margin, a small but crucial margin.
