Control of the quantum interference in a superconducting qubit system
Hao Ying, Da-Wei Luo, Jing‐Bo Xu
We propose a scheme to control quantum interference pattern in a system of a superconducting qubit coupled to its own data bus by applying a controllable time-dependent electromagnetic field. It is shown that the quantum interference induced by the initial phase difference is closely related to the quantum correlations between two superconducting qubits which are coupled to their own data bus and the geometric discord can also be increased by applying the controllable electromagnetic field.
