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

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 ...

Reviews 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 ...

Distributing Multipartite Entanglement over Noisy Quantum Networks [PDF]
Quantum, 2023 A quantum internet aims at harnessing networked quantum technologies, namely by distributing bipartite entanglement between distant nodes. However, multipartite entanglement between the nodes may empower the quantum internet for additional or better ...

Laboratory-frame tests of quantum entanglement in $H \to WW$ [PDF]
, 2022 Quantum entanglement between the two $W$ bosons resulting from the decay of a Higgs boson may be investigated in the dilepton channel $H \to WW \to \ell \nu \ell \nu$ using laboratory-frame observables that only involve the charged leptons $\ell=e,\mu ...

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 ...

Measurement-induced entanglement phase transition on a superconducting quantum processor with mid-circuit readout [PDF]
Nature Physics, 2022 Quantum many-body systems subjected to unitary evolution with the addition of interspersed measurements exhibit a variety of dynamical phases that do not occur under pure unitary evolution. However, these systems remain challenging to investigate on near-
