Fig. 5: Simultaneous parametric reset of Q1, Q2, and effects of reset pulse on adjacent qubits.
From: Rapid and unconditional parametric reset protocol for tunable superconducting qubits
a Time evolution of Q1 (blue) and Q2 (red) \(\left|e\right\rangle\) state population when performing a parametric reset on both qubits simultaneously. The population remains at a steady low level from 2 μs onwards. The pulse sequence for simultaneous parametric reset is inset. b Pulse sequence for Clifford-based randomized benchmarking (RB) on Q2(Q3). During the RB, either a parametric reset (with the same pulse duration as the m Clifford gates) was applied to Q1 or, for comparison, no pulse was applied to Q1. c RB results for the scenario described in b. The error bars are statistical ( ± 1 s.d.) with 30 repetitions. The average single gate fidelity standard deviation is 0.08%(0.03%) for Q2(Q3).
