Microwave Photon Antibunching at the Modulation of the Resonance Frequency of a Qubit Emitter

摘要

The statistics photons in the resonance fluorescence of a qubit excited bymicrowave and radio-frequency (RF) fields have been studied. It has beenestablished that the coherent dissipative dynamics of the qubit with allowancefor multiphoton emission and absorption of RF photons in each act of emissionand absorption of a microwave photon results in periodic alternation of photonbunching and antibunching. It has been shown that periodically varyingstatistics photons can be smoothly transformed to the purely sub-Poissonstatistics by varying the parameters of the RF field. The conditions for theformation of the "collapse-revival" of oscillations in the second-ordercorrelation function photons have been determined. The described effects can beimplemented on spin and superconducting qubits, quantum dots, andqubit-mechanical hybrid systems.
