We investigate a double quantum dot coupled to a transmission line resonator. By driving a current through the double dot, a population inversion between the dot levels can be created, and a lasing state of the radiation field is generated within a sharp resonance window. The transport current correlates with the lasing state. The sharp resonance condition allows for resolving small differences in the dot properties. Dissipative processes in the quantum dots and their effect on the lasing and…

Lasing without inversion in circuit quantum electrodynamics.
TLDR
The photon generation in a transmission line oscillator coupled to a driven qubit in the presence of a dissipative electromagnetic environment is studied to show that the circuit can also exhibit the effect of "lasing without inversion", similar to the recoil effect predicted for atomic systems.
