a Average time of charge-parity jump (τ) versus QP injection power for all selected qubits, normalized to the value at −20 dBm. Data with different darkness is for different qubits. The power spectral densities (PSD) of the charge-parity time evolution for two injection powers indicated by green and orange squares are shown in the inset, which are used to extract τ. As the injection power increases to approximately 4 dBm, τ starts to decrease. b Normalized average time of bit flip (T1) versus QP injection power. The qubit energy relaxations for two injection powers, indicated by green and orange squares, are shown in the inset, which is used to determine T1. T1 is seen to decrease at the injection power of approximately 22 dBm. Source data is provided as a Source Data file.
