The reporter learned from the Institute of Quantum Information and Quantum Science and Technology Innovation of the Chinese Academy of Sciences that on the evening of May 31, the 176-bit "Zuchongzhi" quantum computing cloud platform was officially launched and opened to users around the world. This has set a new record for the number of superconducting quantum computers in my country's cloud platform. It is also the first quantum cloud computing platform in the world that has the potential to realize quantum superiority on the superconducting quantum route and is open to the outside world. It will further promote the development of quantum computing hardware and software and ecological construction.

The roar was coming from the corner of the lobby on the first floor of the University of Science and Technology Guodun Quantum Technology Co., Ltd. The reporter saw a white metal tank protruding from the ceiling, which was connected to several control system chassis through countless wiring harnesses. The temperature and other data are jumping on the screen... This is a running superconducting quantum computer, and inside the metal tank is the core of the quantum computer - the quantum chip. According to reports, the cloud platform launched this time connects users with quantum computing equipment through cloud technology, and supports users to conduct quantum computing experiments and development remotely.
Zhu Xiaobo, a professor at the University of Science and Technology of China and the chief quantum computing engineer of "Zuchongzhi", told reporters that the number of bits is an important indicator to measure the computing power of a quantum computer. The R&D team of the University of Science and Technology of China made an improvement on the basis of the original 66-bit chip of "Zuchongzhi No. 2", and added a control interface of 110 coupling bits, making the number of qubits that users can manipulate reached 176 bits. In addition to the bit scale, in terms of key indicators related to the performance of quantum computers such as connectivity, fidelity, and coherence time, the design indicators of the new generation of quantum computers connected to the "Zuchongzhi" cloud platform are also aimed at the international advanced level, and continuous debugging improves performance. .

It is reported that the threshold for research and development of quantum computers is extremely high, the operating environment is harsh, and the auxiliary equipment is complex. The Chinese Academy of Sciences Quantum Information and Quantum Science and Technology Innovation Institute, the Chinese Academy of Sciences Software Institute, the University of Science and Technology Guodun and other units cooperated to develop core devices, programming languages and software, and jointly built a 176-bit superconducting quantum computer cloud platform.
Peng Chengzhi, deputy commander in chief of quantum computing of "Zuchongzhihao" and chairman of HKUST Guodun, told reporters that the cloud platform is open to users all over the world, and the general public can use the quantum computing cloud platform to experience simple quantum computing programming and image experiments in person. . For industrial users, remote access to quantum computers can further explore new applications.
"The more users of the cloud platform, the more experience in application and development, and the advancement of the entire field. We welcome more people to use and experience." Peng Chengzhi said that in the future, the "Zuchongzhi" quantum computing cloud platform plans to take over Multiple high-performance quantum computers are installed to back up each other and update iteratively to maintain the international advanced level.
