Quantum Entanglement of Monochromatic and Non-Monochromatic Photons on a Waveguide Beam Splitter [PDF]

open access: yesEntropy, 2021
It is well known that the waveguide beam splitter can be used as a source for the quantum entanglement of photons. The analysis of such quantum entanglement is a difficult problem even for monochromatic photons, since the system under study is ...

Entanglement: quantum or classical? [PDF]

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

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,

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.

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.

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.

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.

Cloning of Quantum Entanglement [PDF]

open access: yesPhysical Review Letters, 2020
Quantum no-cloning, the impossibility of perfectly cloning an arbitrary unknown quantum state, is one of the most fundamental limitations due to the laws of quantum mechanics, which underpin the physical security of quantum key distribution. Quantum physics does allow, however, approximate cloning with either imperfect state fidelity and/or ...
