Five-Qubit Quantum Error-Correction of Superposition State
Bao Xiu-li · Journal of Southwest China Normal University · 2007
Based on the quantum error correcting theory of superposition state,this paper constructs,by utilizing the H gates and the CNOT gates,a five-bit error correction circuit of quantum encoding,which can implement the least use of superposition state encoding under the condition of quantum Hamming bound.
