Optimal control of decoherence in the quantum circuit containing superconducting qubits
Yinghua Ji, Juju Hu · 2014
Utilizing the method of optimal control, we investigated the tactics of decoherence suppression in the open quantum circuit system containing superconducting qubits. We first discussed the modeling of the system under the optimal control. Then, we designed a control law by means of optimal control. The simulation results indicate that the flip time of qubits can be effectively manipulated through changing the weight coefficients of the cost function, which provides a new way for manipulating the decoherence.
