Entanglement dynamics in chaotic systems [PDF]
, 2004 We study quantum chaos for systems with more than one degree of freedom, for which we present an analysis of the dynamics of entanglement. Our analysis explains the main features of entanglement dynamics and identifies entanglement-based signatures of ...

Long-Distance Entanglement Purification for Quantum Communication. [PDF]
Physical Review Letters, 2021 High-quality long-distance entanglement is essential for both quantum communication and scalable quantum networks. Entanglement purification is to distill high-quality entanglement from low-quality entanglement in a noisy environment and it plays a key ...

Heralded entanglement distribution between two absorptive quantum memories [PDF]
Nature, 2021 Owing to the inevitable loss in communication channels, the distance of entanglement distribution is limited to approximately 100 kilometres on the ground1. Quantum repeaters can circumvent this problem by using quantum memory and entanglement swapping2.

A quantum router architecture for high-fidelity entanglement flows in quantum networks
npj Quantum Information, 2022 The past decade has seen tremendous progress in experimentally realizing the building blocks of quantum repeaters. Repeater architectures with multiplexed quantum memories have been proposed to increase entanglement distribution rates, but an open ...

On the Second-Order Asymptotics for Entanglement-Assisted Communication [PDF]
, 2016 The entanglement-assisted classical capacity of a quantum channel is known to provide the formal quantum generalization of Shannon's classical channel capacity theorem, in the sense that it admits a single-letter characterization in terms of the quantum ...

Deterministic quantum entanglement between macroscopic ferrite samples
, 2020 We show how macroscopic magnetic samples like yttrium iron garnet samples are excellent candidates for producing deterministic quantum entanglement and, thus, providing a platform for quantum information science. This requires strong coupling with a high

How discord underlies the noise resilience of quantum illumination
New Journal of Physics, 2016 The benefits of entanglement can outlast entanglement itself. In quantum illumination, entanglement is employed to better detect reflecting objects in environments so noisy that all entanglement is destroyed.

General polygamy inequality of multi-party quantum entanglement
, 2012 Using entanglement of assistance, we establish a general polygamy inequality of multi-party entanglement in arbitrary dimensional quantum systems. For multi-party closed quantum systems, we relate our result with the monogamy of entanglement to show that

Entanglement purification on quantum networks
Physical Review Research, 2023 We present an approach to entanglement purification on complex quantum network architectures, that is, how a quantum network built from repeaters with limited processing fidelity can purify and distribute entanglement between users.
