Abstract

We present several experimental progresses for advanced quantum communication based on multi-photon entanglement. Quantum secret sharing (QSS) and third-man quantum cryptograph (TQC) shows the advancement in multi-party quantum communication. Quantum error rejection (QER) holds the promise for error-free transfer in long-distance quantum communication. Fault-tolerant quantum cryptography in a decoherence-free subspace (DFS) and quantum-relay-assisted key distribution respectively overcome the difficulties caused by decoherence and photon loss, the two main crucial problems in long-distance quantum communication.
