Readout-induced degradation of transmon lifetimes: interplay of TLSs and qubit spectral reshaping

Ziwen Huang, Jimmy Shih-Chun Hung, Mouktik Raha +9

Measurement backaction degrades dispersive readout of superconducting qubits even at modest drive strengths, often via the reduction of qubit lifetimes during readout. In this work…
