摘要：
A quantum secure direct communication protocol over a collective rotating channel is proposed. Theprotocol encodes logical bits in noiseless subspaces, and so it can function over a quantum channel subjected to anarbitrary degree of collective rotating noise. Although entangled states are used, both the sender and receiver are onlyrequired to perform single-particle product measurement or Pauli operations. The protocol is feasible with present-daytechnique.
