Dynamic Polariton and Quantum State Swapping Between an Electromagnetic Field and Atomic Ensemble

摘要：We analyse a dynamical swapping of the quantum state in coupled harmonic oscillatros,the result can be applied to the interaction of a single-mode field with atomic ensemble in the weak field case,Similar to the case of electromagnetic induced transparency(EIT),a dynamic polariton is formed.Therefore,the quantum state of the field can be completely mapped on to the atomic medium,and vice versa,Using this dynamical swapping and the adiabatic transfer in the EIT between the field and atomic ensemble,we propose a scheme in which both the quantum and the coherent information can be transferred from one field to another. | |
