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…
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…
Geometric signature of non-Markovian dynamics
Da-Wei Luo, Ting Yu
Non-Markovian effects in the dynamics of an open system are typically characterized by non-monotonic information flows from the system to its environment or by information backflow…
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…
