Entanglement islands read perfect-tensor entanglement

Journal of High Energy Physics
In this paper, we make use of holographic Boundary Conformal Field Theory (BCFT) to simulate the black hole information problem in the semi-classical picture.

Entanglement reactivation in separable environments

New Journal of Physics, 2013
Combining two entanglement-breaking channels into a correlated-noise environment restores the distribution of entanglement. Surprisingly, this reactivation can be induced by the injection of separable correlations from the composite environment.

Entanglement buffering with multiple quantum memories

npj Quantum Information
Entanglement buffers are systems that maintain high-quality entanglement, ensuring it is readily available for consumption when needed. We study the performance of a two-node buffer, where each node has one long-lived quantum memory for entanglement ...

Distillable entanglement under dually non-entangling operations

Nature Communications
Computing the exact rate at which entanglement can be distilled from noisy quantum states is one of the longest-standing questions in quantum information. We give an exact solution for entanglement distillation under the set of dually non-entangling (DNE)

Measuring statistics-induced entanglement entropy with a Hong–Ou–Mandel interferometer

Nature Communications
Despite its ubiquity in quantum computation and quantum information, a universally applicable definition of quantum entanglement remains elusive. The challenge is further accentuated when entanglement is associated with other key themes, e.g., quantum ...

Genuinely accessible and inaccessible entanglement in Schwarzschild black hole

Physics Letters B
The genuine entanglement of Dirac fields for an N-partite system is investigated in Schwarzschild spacetime and the analysis is carried out using the single-mode approximation.
