Transfer of an unknown quantum state, quantum networks, and memory
Asoka Biswas, G. S. Agarwal
abstract: 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 $\Lambda$ 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 contaning one photon.
