T<sub>1</sub> renormalization of transmon qubits versus drive power

ORAL

Abstract

Recent experiments in circuit QED with a transmon qubit have found a strong dependence of the qubit relaxation rate on the read-out drive power [1]. We discuss a plausible mechanism that is consistent with available experimental data up to intermediate drive powers (cavity occupation n < 7).
