Coherent State Control to Recover Quantum Entanglement and Coherence
How to analytically deal with the entanglement and coherence dynamics of separated Jaynes−Cummings nodes with continuous-variable fields is still an open question. We here generalize this model to a more common situation including either a small or

Acceleration-assisted entanglement harvesting and rangefinding
We study entanglement harvested from a quantum field through local interaction with Unruh–DeWitt detectors undergoing linear acceleration. The interactions allow entanglement to be swapped locally from the field to the detectors.

We explore the quantum-memory assisted entropic uncertainty (QMA-EU), Jensen-Shannon coherence and entanglement dynamics in a Graphene sheet of disordered electrons in the presence of the intrinsic decoherence.

Entanglement harvesting and quantum discord of alpha vacua in de Sitter space
The CPT invariant vacuum states of a scalar field in de Sitter space, called α-vacua, are not unique. We explore the α-vacua from the quantum information perspective by a pair of static Unruh-DeWitt (UDW) detectors coupled to a scalar field with either ...

Sudden death and revival of Gaussian Einstein–Podolsky–Rosen steering in noisy channels
Einstein–Podolsky–Rosen (EPR) steering is a useful resource for secure quantum information tasks. It is crucial to investigate the effect of inevitable loss and noise in quantum channels on EPR steering.

Hawking effect can generate physically inaccessible genuine tripartite nonlocality
We explore the acceleration effect on the genuine tripartite nonlocality (GTN) for one or two accelerated detector(s) coupled to the vacuum field with initial mixed tripartite states.

Experimental observation of environment-induced sudden death of entanglement [PDF]
We demonstrate the difference between local, single-particle dynamics and global dynamics of entangled quantum systems coupled to independent environments. Using an all-optical experimental setup, we show that, while the environment-induced decay of each system is asymptotic, quantum entanglement may suddenly disappear.
