abstract = {We study a superconducting artificial atom which is
represented by a single Josephson junction or a Josephson
junction chain, capacitively coupled to a coherently driven
transmission line, and which contains exactly one residual
quasiparticle (or less than one quasiparticle per island in
a chain). We study the dissipation in the atom induced by
the quasiparticle tunneling, taking into account the
quasiparticle heating by the drive. We calculate the
transmission coefficient in the transmission line for drive
frequencies near resonance and show that, when the
artificial atom spectrum is nearly harmonic, the intrinsic
quality factor of the resonance increases with the drive
power. This counterintuitive behavior is due to the energy
dependence of the quasiparticle density of states.},
