Quantum entanglement recognition [PDF]
Physical 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

Reviews of Modern Physics, 2009 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 dinger - waited over 70 years to enter to laboratories as a new resource as real as energy. This holistic

Quantum Entanglement of Monochromatic and Non-Monochromatic Photons on a Waveguide Beam Splitter [PDF]
Entropy, 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]
Reports 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]
Physical 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.

Transitions in Entanglement Complexity in Random Circuits [PDF]
Quantum, 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.

Cloning of Quantum Entanglement [PDF]
Physical 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 ...

The Effect of Quantum Noise on Multipartite Entanglement from a Cascaded Parametric Amplifier
Photonics, 2023 The tripartite entanglement generated from a cascaded parametric amplifier is always present in the whole gain region in the ideal condition. However, in practical applications, the quantum entanglement is very fragile and easily deteriorated by quantum ...
