信息理论的新进展——量子信息论与量子神经计算

New Development of Information Theory——Quantum Information Theory and QuantumNeural Computing

正如信息论是现有通信和信息处理的理论指导一样,基于量子力学原理的量子信息论将成为下一代通信模式———量子通信的理论基础,量子计算与神经计算相结合的量子神经计算将成为未来信息处理的重要手段。从量子信息基础出发,讨论量子信息论和量子神经计算两个方面,前者涉及量子信源编码、量子纠错编码、量子信道容量计算以及量子信息加密等内容;后者涉及量子神经计算基本原理。并就量子信息理论与现有信息论、经典神经网络与量子神经网络之间的异同之处加以比较。

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.
