METHOD FOR CORRECTING ERROR OF IMPERFECT ENTANGLED QUBIT IN RECEIVER

摘要

The present invention relates to an EA-CWS quantum error-correcting code that corrects an imperfect entangled qubit error. The error correcting method using entangled qubits which a transmitter and a receiver share carries out an encoding process for transmitting the entangled qubits, and then calculates a Pauli error of EA-CWS code with respect to different stabilizer generators. The calculated error in either the transmitter and the receiver is converted into error-correcting code that can be corrected. The method then corrects the entangled qubit error in either the transmitter and the receiver by generating a word operator for the CWS code by using the converted error-correcting code.;COPYRIGHT KIPO 2015
