Abstract: Coupling quantum-dot circuits to microwave photons allows one to study the photon-assisted quantum transport. Here, we revisit this typical circuit quantum electrodynamical setup by introducing the Kerr nonlinearity of photons. By exploiting a quantum critical behavior, we propose a powerful scheme to control the power harvesting efficiency in the microwave regime, where the driven-dissipative optical system acts as an energy pump. It drives electron transport against a load in quantum-dot circuit. The energy … Show more
