Transfer of an unknown quantum state, quantum networks, and memory
Asoka Biswas, Girish Saran Agarwal · Physical Review A · 2004
We present a protocol for transfer of an unknown quantum state. The protocol is based on a two-mode cavity interacting dispersively in a sequential manner with three-level atoms in the $\ensuremath{\Lambda}$ configuration. We propose a scheme for quantum networking using an atomic channel. We investigate the effect of cavity decoherence in the entire process. Further, we demonstrate the possibility of an efficient quantum memory for arbitrary superposition of two modes of a cavity containing one photon.
