A mapping method to improve fidelity of quantum circuits
NIU Yiren, GUAN Zhijin, MA Tianhong, and JIN Shengxiang
The error of the double-qubit gate operation caused by the noise is an important reason for the reduction of the fidelity of the execution result in the reversible quantum circuit. A strategy for mapping quantum circuits to noisy quantum computing devices is proposed, so as to improve the success rate of quantum circui
