Optimized Unconventional Geometric Gates in Superconducting Circuits

Nonadiabatic Abelian geometric quantum computation has been extensively studied, due to its fast manipulation and inherent noise resistance. However, obtain the pure phase, state is required evolve along some special paths eliminate dynamical phase. This leads increasing evolution time weakened gate robustness. The unconventional an effective way solve above problems. Here, we propose a general approach realize computation. Then, discuss effect of ratio phase dynamic on performance gates. results show that selection corresponds different Therefore, can optimize get higher-fidelity At last, construct ratio-optimized gates in superconducting circuit test fidelities T-gate, Hadamard H-gate, controlled be obtained as 99.98%, 99.95%, 99.85%, respectively. our scheme provides promising large-scale fault-tolerant circuits.
