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.

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-

Topologically protected quantum entanglement emitters
Nature Photonics, 2021 Entanglement and topology portray nature at the fundamental level but differently. Entangled states of particles are intrinsically sensitive to the environment, whereas the topological phases of matter are naturally robust against environmental ...

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 ...

Detecting a Target With Quantum Entanglement [PDF]
IEEE Aerospace and Electronic Systems Magazine, 2020 Over the last decade, research activity has focused on the use of quantum entanglement as a resource for remote target detection, i.e., on the design of a quantum radar.

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.

Mixed-state entanglement and quantum error correction. [PDF]
Physical Review A. Atomic, Molecular, and Optical Physics, 1996 Entanglement purification protocols (EPPs) and quantum error-correcting codes (QECCs) provide two ways of protecting quantum states from interaction with the environment. In an EPP, perfectly entangled pure states are extracted, with some yield D, from a
