Abstract:

A new quantum secure direct communication (QSDC) protocol is proposed byusing decoherence free subspace (DFS) to avoid insecurity of the presentQSDC protocols in a quantum noise channel. This protocol makes it easily for Bob and Alice to find eavesdropping in channel because the collective dephasing noise disappears in DFS. The probability of successful attack by Eve in this protocol is smaller than in BB84 protocol. Thus this protocol realizes secure QSDC and is feasible with present-day technology.
