Recent Progress in Superconducting Quantum Computing at USTC

Superconducting quantum computing has emerged as a promising platform for early-stage quantum computing experiments, driven by the fabrication and control advantages of mature technologies—specifically semiconductor fabrication and microwave control. To advance Noisy Intermediate-Scale Quantum (NISQ) applications and realize fault tolerance, more advanced quantum processors and complex yet robust calibration protocols are required.

This talk will present recent progress in superconducting quantum computing at the University of Science and Technology of China (USTC). We have upgraded our quantum processor to Zuchongzhi 3.0—a more powerful superconducting quantum computing prototype featuring 105 qubits and exceptionally high-fidelity operational capabilities. Leveraging this state-of-the-art prototype, we have achieved two key results: random circuit sampling (RCS) using 83 qubits over 32 cycles; genuine entanglement of 95 qubits;
