Quantum Entanglement and Communication Complexity [PDF]

open access: greenBRICS Report Series, 2001
We consider a variation of the multi-party communication complexity scenario where the parties are supplied with an extra resource: particles in an entangled quantum state.

Quantum entanglement recognition [PDF]

open access: yesPhysical Review Research, 2021
Entanglement constitutes a key characteristic feature of quantum matter. Its detection, however, still faces major challenges. In this paper, we formulate a framework for probing entanglement based on machine learning techniques. The central element is a

Quantum entanglement [PDF]

open access: yesReviews of Modern Physics, 2007
All our former experience with application of quantum theory seems to say: {\it what is predicted by quantum formalism must occur in laboratory}. But the essence of quantum formalism - entanglement, recognized by Einstein, Podolsky, Rosen and Schr ...

Computing quantum discord is NP-complete

open access: yesNew Journal of Physics, 2014
We study the computational complexity of quantum discord (a measure of quantum correlation beyond entanglement), and prove that computing quantum discord is NP-complete.

Entanglement: quantum or classical? [PDF]

open access: yesReports on Progress in Physics, 2020
From its seemingly non-intuitive and puzzling nature, most evident in numerous EPR-like gedankenexperiments to its almost ubiquitous presence in quantum technologies, entanglement is at the heart of modern quantum physics. First introduced by Erwin Schr dinger nearly a century ago, entanglement has remained one of the most fascinating ideas that came ...

Entangled quantum memristors [PDF]

open access: yesPhysical Review A, 2021
We propose the interaction of two quantum memristors via capacitive and inductive coupling in feasible superconducting circuit architectures. In this composed system the input gets correlated in time, which changes the dynamic response of each quantum memristor in terms of its pinched hysteresis curve and their nontrivial entanglement.

Device-independent characterization of entanglement based on bell nonlocality

open access: yesFundamental Research, 2021
Quantum entanglement, has been acknowledged as a precious resource due to its inherent nonclassical correlations between subsystems. These quantum correlations have the potential for many quantum processes, including canonical ones: quantum cryptography,

Transitions in Entanglement Complexity in Random Circuits [PDF]

open access: yesQuantum, 2022
Entanglement is the defining characteristic of quantum mechanics. Bipartite entanglement is characterized by the von Neumann entropy. Entanglement is not just described by a number, however; it is also characterized by its level of complexity.
