On August 4, Genyuan Quantum announced that it and a research team from the University of Science and Technology of China have made new progress in fast high-fidelity two-bit quantum gate control. Related work was published in the top international physics journal Physical Review Letters under the title “Combating the Speed-Fidelity Trade-Off in Fast CZ via Cyclic Control”. In response to the speed-fidelity trade-off caused by short-term waveform distortion in superconducting quantum chips, the team proposed a controlled phase gate scheme for parameter space expansion, which significantly suppresses correlation errors without extending gate time. This result was completed on the “Gengen Goku” superconducting quantum computer.
