In early March 2025, researchers at China University of Science and Technology (USTC) reported on the development of an advanced superconducting quantum computer Zuchongzhi-3 that is said to be laying the groundwork for a whole new era of computing. According to the developers, the Zuchongzhi-3 is one million times faster than the quantum processor Google Sycamore.
Zuchongzhi-3 has 105 qubits against 54 for Google Sycamore. According to Chinese researchers, in solving certain problems, the new quantum system in performance is 15 orders of magnitude ahead of the most powerful modern supercomputers with traditional architecture. Zuchongzhi-3 was tested on random quantum circuit sampling problems. The device demonstrates a coherence time of 72 μs, the accuracy of single-bit operations is about 99.9%, two-bit operations - 99.62%. The accuracy of parallel reading reaches 99.13%.
To assess the capabilities of the system, experts sampled random quantum circuits with 83 qubits and 32 layers. The new quantum computer was able to cope with the task quadrillion times faster than the time it would take the most powerful classical supercomputer.
The creators of Zuchongzhi-3 continue active research in the fields of quantum error correction, quantum entanglement, quantum modeling and quantum chemistry. The achievement shown marks an important milestone in improving the performance of quantum computing. Zuchongzhi-3 has demonstrated quantum superiority - the ability of a quantum computer to solve problems that are, in principle, impossible for classical computers or require extremely much time to perform calculations.
