Quantum entanglement in helium [PDF]

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2011
We compute the entanglement of the ground state and several singlet and triplet excited states of the helium atom using high-quality, state-of-the-art wavefunctions. The behaviour of the entanglement of the helium eigenstates is similar to that observed in some exactly soluble two-electron systems. In particular, the amount of entanglement exhibited by

Doubling the Size of Quantum Simulators by Entanglement Forging [PDF]

open access: yesPRX 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.

Monogamy of Quantum Entanglement

open access: yesFrontiers 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.

Quantum entanglement on boundaries [PDF]

open access: yesJournal of High Energy Physics, 2013
Quantum entanglement in 3 spatial dimensions is studied in systems with physical boundaries when an entangling surface intersects the boundary. We show that there are universal logarithmic boundary terms in the entanglement R nyi entropy and derive them for different conformal field theories and geometrical configurations. The paper covers such topics

Genuine multipartite entanglement measures based on multi-party teleportation capability

open access: yesScientific 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.

Entanglement and quantum groups [PDF]

open access: yesJournal 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.

Observable quantum entanglement due to gravity [PDF]

open access: yesnpj 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 ...
