摘要

We study an N-type cesium atomic system to investigate the influence of coupling fields on single-photon Fock states of a probe field passing through an electromagnetically induced transparency (EIT) medium. These results demonstrate the potential for effective control of the EIT effect through selective manipulation of the quantum characteristics of the coupling fields. To appraise the propagation and quantum fidelity of single-photon Fock states by using general reservoir theory (GRT) and a mean-field expansion approach, allowing us to determine the transmitted probe field’s quantum state while considering fluctuations in strong coupling fields and the expected EIT response using a semi-classical model. We theoretically explore the possibility of improving and manipulating the transmittance and quantum fidelity of probe photons by increasing the Rabi frequency of the control fields. This improvement in the quantum fidelity and transmission of probe photons Fock-state represents a major advance in the fields of teleportation, quantum memory, error-free quantum computing, and quantum communications.
