Fidelity Dynamics of a Jaynes--Cummings Qubit under Markovian and Non-Markovian Coupling Noise
Fang Wang, Da-Wei Luo, Ting Yu
We analytically investigate the fidelity dynamics of a Jaynes--Cummings qubit coupled to a single-mode cavity in the presence of stochastic fluctuations of the qubit--cavity coupli…
Receiver-Constrained Recovery Placement for Encoded-Qutrit Teleportation under Monitored Decay

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…
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…
