Learning Non-Markovian Noise via Ensemble Optimal Control
Da-Wei Luo, Ting Yu
We study the estimation of parameters pertaining to non-Markovian quantum open systems, such as the dissipation rate and environmental memory time. A key challenge is identifying t…
Optimal transfer of entanglement in oscillator chains in non-Markovian open systems
Da-Wei Luo, Edward Yu, Ting Yu
We considered the transfer of continuous-variable entangled states in coupled oscillator chains embedded in a generic environment. We demonstrate high-fidelity transfer via optimal…
Quantum Fisher Information and the Curvature of Entanglement
Zain H. Saleem, Anil Shaji, Anjala M Babu +4
We explore the relationship between quantum Fisher information (QFI) and the negative of the second derivative of concurrence with respect to the coupling between two qubits, refer…
Optimal entanglement generation in optomechanical systems via Krotov control of covariance matrix dynamics
Pengju Chen, Da-Wei Luo, Ting Yu
We investigated the optimal control of a continuous variable system, focusing on entanglement generation in an optomechanical system without utilizing Fock basis cutoffs. Using the…
Jaynes-Cummings atoms coupled to a structured environment: Leakage elimination operators and the Petz recovery maps
Da-Wei Luo, Ting Yu
We consider the Jaynes-Cummings (JC) model embedded in a structured environment, where the atom inside an optical cavity will be affected by a hierarchical environment consisting o…
Time-reversal assisted quantum metrology with an optimal control
Da-Wei Luo, Ting Yu
We propose a protocol to overcome the shot noise limit and reach the Heisenberg scaling limit for parameter estimation by using quantum optimal control and a time-reversal strategy…
