Genuine multipartite entanglement measures based on multi-party teleportation capability
Scientific Reports, 2023 Quantifying entanglement is vital to understand entanglement as a resource in quantum information processing, and many entanglement measures have been suggested for this purpose.

The squashed entanglement of the noiseless quantum Gaussian attenuator and amplifier [PDF]
, 2019 We determine the maximum squashed entanglement achievable between sender and receiver of the noiseless quantum Gaussian attenuators and amplifiers and we prove that it is achieved sending half of an infinitely squeezed two-mode vacuum state.

Entanglement and quantum groups [PDF]
Journal of Mathematical Physics, 2009 We describe quantum mechanical entanglement in terms of compact quantum groups. We prove an analog of positivity of partial transpose criterion and formulate a Horodecki-type theorem.

Monogamy of Quantum Entanglement
Frontiers in Physics, 2022 Unlike classical correlation, quantum entanglement cannot be freely shared among many parties. This restricted shareability of entanglement among multi-party systems is known as monogamy of entanglement, which is one of the most fundamental properties of entanglement.

Doubling the Size of Quantum Simulators by Entanglement Forging [PDF]
PRX Quantum, 2021 Quantum computers are promising for simulations of chemical and physical systems, but the limited capabilities of today's quantum processors permit only small, and often approximate, simulations.

Sensitivity of entanglement measures in bipartite pure quantum states [PDF]
Modern Physics Letters B 2022; 36 (22): 2250101, 2022 Entanglement measures quantify the amount of quantum entanglement that is contained in quantum states. Typically, different entanglement measures do not have to be partially ordered. The presence of a definite partial order between two entanglement measures for all quantum states, however, allows for meaningful conceptualization of sensitivity to ...

Observable quantum entanglement due to gravity [PDF]
npj Quantum Information, 2019 No experiment to date has provided evidence for quantum features of the gravitational interaction. Recently proposed tests suggest looking for the generation of quantum entanglement between massive objects as a possible route towards the observation 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 ...
