Fig. 3: Maximum state leakage for different coupling strengths and temperatures.
From: State leakage during fast decay and control of a superconducting transmon qubit
Maximum state leakage for the decay from the first excited state calculated with SLED. Note that blue and green lines almost overlap each other. Dotted lines indicate the steady-state thermal leakage calculated using the Boltzmann distribution for βℏω01 = 2. Here EJ/EC = 100, ωc = 50ω01, and N = 5.
