Anhui Quantum Computing Chip Key Laboratory says a joint team from Benyuan
Quantum and the University of Science and Technology of China proposed a
parameter-space-extended controlled-phase gate (PSE-CZ) that addresses the
long-standing speed versus fidelity constraint in superconducting quantum
computing, enabling faster two-qubit gates with substantially higher precision.
The results are published in Physical Review Letters and were experimentally
validated on China’s domestically developed superconducting quantum computer
"Benyuan Wukong".
