Quantum Turbo codes
量子Turbo码

Quantum error correction coding technology is of great importance for quantum communication as well as quantum computation.Nearly all of the classical error correction coding schemes have, for the time being, been transplanted to the domain of quantum information;nevertheless, the most outstanding scheme in classical coding region, turbo code,still lacks the quantum analogy till now.We have completed a simple scheme of quantum recursive systematic convolutional code by means of quantum register network.At the same time, a kind of efficient quantum interweaver is constructed using only quantum SWAP gates.Also a serially concatenated quantum Turbo code is developed by analogy to the classical Turbo code.As limited by the quantum non-cloning theorem, the proposed quantum turbo code is serially concatenated.Quantum turbo code may not only extend the research area of quantum error correction coding technology, but also solve the puzzle in classical coding theory.
