Abstract
The statistics of photons in the resonance fluorescence of a qubit excited by microwave and radio-frequency (RF) fields have been studied. It has been established that the coherent dissipative dynamics of the qubit with allowance for multiphoton emission and absorption of RF photons in each act of emission and absorption of a microwave photon results in periodic alternation of photon bunching and antibunching. It has been shown that periodically varying statistics of photons can be smoothly transformed to the purely sub-Poisson statistics by varying the parameters of the RF field. The conditions for the formation of the “collapse-revival” of oscillations in the second-order correlation function of photons have been determined. The described effects can be implemented on spin and superconducting qubits, quantum dots, and qubit-mechanical hybrid systems.
