Quantum Operation for One Non-Markovian Qubit via AC Control
This paper studies the simple alternating-current (AC)control strategy for performing quantum state manipulation under a non-Markovian environment (consisting of a cluster of two-level systems).Genetic algorithm is adopted to optimize the parameters of the AC control to fulfil one-qubit quantum operations,such as the NOT gate,the Z gate,and the Hadamard gate. Theoretical analysis and simulations show that our method can keep the Rabi frequency of the system away from the noise band so as to suppress low-frequency 1 /f noise.In the meantime,the strategy can also drive the quantum state to the target state with high fidelities.
