Abstract: | This paper proposes an efficient scheme for quantum
communication between two atoms trapped in distant cavities which
are connected by an optical fibre. During the operation, all the atomic system,
the cavity modes and the fibre are not excited. The quantum state
is mediated by the vacuum fields. The idea can be used to realize
quantum entanglement between two distant atoms via vacuum. |
