New Development of Information Theory——Quantum Information Theory and QuantumNeural Computing

Just as information theory, quantum information theory which based on quantum mechanics will become the direction of next quantum telecommunication and information procwssing. The fields of quantum information and quantumneural computing are discussed in this article, in particular, the fundamentals of the field, source coding, quantum error correcting codes, capacities of quantum channels and quantum cryptography, and the comparison between quantum information theory and information theory and the comparison between neural computing and quantumneural computing are also given.
