【摘要】Using the generalized Bell states and quantum gates, we introduce a quantum encryption scheme of d-level states (qudits). The scheme can detect and correct arbitrary transmission errors using only local
operations
and
classical
communications
between
the
communicators. In addition, the entanglement key used to encrypt can be recycled. The protocol is informationally secure, because the output state is a totally mixed one for every input state p. 【总页数】5页(1690-1694)
