Overcoming the Speed-Fidelity Trade-off in Fast CZ Gates via Cyclic Control
Ze-An Zhao, Hai-Feng Zhang, Tian-Le Wang +10
High-fidelity quantum gates are essential for scalable quantum computation. However, at short durations, short-timescale waveform distortions break the time-reflection symmetry of…

Single-Step Phase-Engineered Pulse for Active Readout Cavity Reset in Superconducting Circuits
Ren-Ze Zhao, Ze-An Zhao, Tian-Le Wang +9
In a circuit QED architecture, we experimentally demonstrate a hardware-efficient and qubit-state-dependent Single-Step Phase-Engineered (SSPE) pulse scheme for actively depopulati…
