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 ...

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 ...

QUANTUM ENTANGLEMENT IN THE MULTIVERSE [PDF]
Журнал Экспериментальной и Теоретической Физики, 2014 In this paper it is shown that the quantum state of a multiverse made up of classically disconnected regions of the space-time, whose dynamical evolution is dominated by a homogeneous and isotropic fluid, is given by a squeezed state. These are typical quantum states that have no classical counterpart and, therefore, they allow us to analyze the ...

Quantum entanglement and topological entanglement [PDF]
New Journal of Physics, 2002 This paper discusses relationships between topological entanglement and quantum entanglement. Specifically, we propose that for this comparison it is fundamental to view topological entanglements such as braids as "entanglement operators" and to associate to them unitary operators that are capable of creating quantum entanglement.

Blindly verifying partially unknown entanglement
iScience, 2022 Summary: Quantum entanglement has shown distinguished features beyond any classical state. Many methods have been presented to verify unknown entanglement with the complete information about the density matrices by quantum state tomography. In this work,

Exponential Clustering of Bipartite Quantum Entanglement at Arbitrary Temperatures
Physical Review X, 2022 Many inexplicable phenomena in low-temperature many-body physics are a result of macroscopic quantum effects. Such macroscopic quantumness is often evaluated via long-range entanglement, that is, entanglement in the macroscopic length scale.
