Quantum computing for smart grid applications

open access: yesIET Generation, Transmission & Distribution, 2022
Computational complexities in modern power systems are reportedly increasing daily, and it is anticipated that traditional computers might be inadequate to provide the computation prerequisite in future complex power grids. In that given context, quantum

On Entanglement Assisted Classical Optical Communications

open access: yesIEEE Access, 2021
Entanglement assisted communication is advocated by numerous authors as an alternative to classical communication offering significant improvement in channel capacity, in particular in noisy regime.

Investigation of Entanglement in the Moshinsky Atom [PDF]

open access: yesفیزیک کاربردی ایران, 2023
One of the most critical aspects of studying entanglement states is quantifying the degree of entanglement. One of the entanglement measures for pure states is Van- Neumann entropy, which is why Van-Neumann entropy is also called entanglement entropy. In

Entanglement and Decoherence: Fragile and Robust Entanglement [PDF]

open access: yesPhysical Review Letters, 2011
The destruction of entanglement of open quantum systems by decoherence is investigated in the asymptotic long-time limit. Starting from a general and analytically solvable decoherence model which does not involve any weak-coupling or Markovian assumption it is shown that two fundamentally different classes of entangled states can be distinguished ...

Gravity as entanglement, entanglement as gravity [PDF]

open access: yesSSRN Electronic Journal, 2020
A generalized and unifying viewpoint to both general relativity and quantum mechanics and information is investigated. It may be described as a generaliztion of the concept of reference frame from mechanics to thermodynamics, or from a reference frame linked to an element of a system, and thus, within it, to another reference frame linked to the whole ...

Entanglement Combing [PDF]

open access: yesPhysical Review Letters, 2009
We show that all multi-partite pure states can, under local operations, be transformed into bi-partite pairwise entangled states in a "lossless fashion": An arbitrary distinguished party will keep pairwise entanglement with all other parties after the asymptotic protocol - decorrelating all other parties from each other - in a way that the degree of ...

WITNESSED ENTANGLEMENT [PDF]

open access: yesInternational Journal of Quantum Information, 2006
We present a new measure of entanglement for mixed states. It can be approximately computable for every state and can be used to quantify all different types of multipartite entanglement. We show that it satisfies the usual properties of a good entanglement quantifier and derive relations between it and other entanglement measures.

Shaping contours of entanglement islands in BCFT

open access: yesJournal of High Energy Physics, 2022
In this paper, we study the fine structure of entanglement in holographic two-dimensional boundary conformal field theories (BCFT) in terms of the spatially resolved quasilocal extension of entanglement entropy — entanglement contour.

Is `entanglement' always entangled? [PDF]

open access: yesJournal of Optics B: Quantum and Semiclassical Optics, 2002
Entanglement, including ``quantum entanglement,'' is a consequence of correlation between objects. When the objects are subunits of pairs which in turn are members of an ensemble described by a wave function, a correlation among the subunits induces the mysterious properties of ``cat-states.'' However, correlation between subsystems can be present from
