China’s Zuchongzhi-3 Processor, A Major Breakthrough ? In a groundbreaking achievement, researchers at the University of Science and Technology of China (USTC) have successfully developed a 105-qubit superconducting quantum processor, Zuchongzhi-3, which operates at a speed 10¹⁵ times faster than the world’s fastest supercomputer. This remarkable breakthrough marks a significant milestone in the development of quantum computing technology.
Quantum Supremacy and the Zuchongzhi-3 Processor
Quantum supremacy refers to the demonstration of a quantum computer’s ability to perform tasks that are infeasible for classical computers. In 2019, Google’s 53-qubit Sycamore processor achieved quantum supremacy by completing a random circuit sampling task in 200 seconds, a task that would have taken approximately 10,000 years to simulate on the world’s fastest supercomputer at the time.
The Zuchongzhi-3 Processor: A Major Breakthrough
The Zuchongzhi-3 processor, developed by USTC researchers, features 105 qubits and 182 couplers, integrated on the same chip to perform quantum random circuit sampling tasks. The processor achieves a coherence time of 72 μs, a parallel single-qubit gate fidelity of 99.90%, a parallel two-qubit gate fidelity of 99.62%, and a parallel readout fidelity of 99.13%.
Enhanced Performance and Quantum Computational Advantage
To evaluate the capabilities of the Zuchongzhi-3 processor, the research team conducted an 83-qubit, 32-layer random circuit sampling task on the system. The results demonstrated that the processor operates at a speed that surpasses the world’s fastest supercomputer by 15 orders of magnitude. Furthermore, the processor outperforms the latest results published by Google by 6 orders of magnitude, establishing the strongest quantum computational advantage in the superconducting system to date.
Quantum Computing Concepts
