Abstract: Noise is currently unavoidable in quantum communication environments. Eavesdroppers can exploit this issue by disguising themselves as channel noise to avoid detection during eavesdropping checks performed by legitimate communicants. This paper first proposes a new… read more here.

DOI: 10.1007/s11128-017-1523-0
Abstract: Different from the previous works on generating entangled states, this work is focused on how to transfer the prepared entangled states onto memory qubits for protecting them against decoherence. We here consider a physical system… read more here.

DOI: 10.1007/s11128-019-2315-5
Abstract: We propose an optical scheme to encode quantum information into three-photon decoherence-free states (single logical qubit information) and thereby acquire immunity from collective decoherence. Our scheme consists of quantum dots (QDs) within single-sided optical cavities… read more here.

DOI: 10.1103/physreva.96.043860
Abstract: We investigate the dynamics of a generic interacting many-body system under conditions of electromagnetically induced transparency (EIT). This problem is of current relevance due to its connection to non-linear optical media realized by Rydberg atoms.… read more here.

DOI: 10.1103/physreva.97.042123
Abstract: Two initially correlated coherent states, each interacting with its own independent dissipative environment exhibit a sudden transition from classical to quantum decoherence. This change in the dynamics is a turning point in the decoherence, in… read more here.
