Quantum steering and nonlocal advantage of quantum coherence in non-Markovian environment

Su-Wan Tu, De-Feng Liu, Cheng‐Cheng Liu +3 more

In the field of quantum information science, quantum steering (QS) and nonlocal advantage of quantum coherence (NAQC) are the core quantum resources, while their practical applications are often limited by the decoherence effect caused by environmental noise in open quantum systems. In this study, we explore the dynamic characteristics of QS and NAQC in non-Markovian environment. It is shown that both QS and NAQC exhibit oscillatory revival, and the amplitude is positively correlated with the purity of the initial state. It is worth mentioning that QS shows greater robustness during recovery, while NAQC decays more significantly under the same conditions. Furthermore, we propose a quantum control strategy based on weak measurement operation and demonstrate that this operation effectively suppresses the decoherence of QS and NAQC in non-Markovian environment.

Optimal control of non-Markovian open quantum systems via feedback

Zairong Xi, Wei Cui, Yu Pan

The problem of optimal control of non-Markovian open quantum system via weak measurement is presented. Based on the non-Markovian master equation, we evaluate exactly the non-Markovian effect on the dynamics of the system of interest interacting with a dissipative reservoir. We find that the non-Markovian reservoir has dual effects on the system: dissipation and backaction. The dissipation exhausts the coherence of the quantum system, whereas the backaction revives it. Moreover, we design the control Hamiltonian with the control laws attained by the stochastic optimal control and the corresponding optimal principle. At last, we considered the exact decoherence dynamics of a qubit in a dissipative reservoir composed of harmonic oscillators, and demonstrated the effectiveness of our optimal control strategy. Simulation results showed that the coherence will completely lost in the absence of control neither in non-Markovian nor Markovian system. However, the optimal feedback control steers it to a stationary stochastic process which fluctuates around the target. In this case the decoherence can be controlled effectively, which indicates that the engineered artificial reservoirs with optimal feedback control may be designed to protect the quantum coherence in quantum information and quantum computation.
