Quantum Entanglement and Its Application in Quantum Communication
Journal of Physics: Conference Series, 2021 Since the concept of quantum entanglement was proposed, quantum entanglement has been paid more and more attention. Especially in recent years, with the interdisciplinary and interdisciplinary development of quantum informatics, the general definition ...

Multidimensional quantum entanglement with large-scale integrated optics [PDF]
Science, 2018 Large-scale integrated quantum optics The ability to pattern optical circuits on-chip, along with coupling in single and entangled photon sources, provides the basis for an integrated quantum optics platform. Wang et al.

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 ...

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

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.

The controlled SWAP test for determining quantum entanglement [PDF]
Quantum Science and Technology, 2020 Quantum entanglement is essential to the development of quantum computation, communications, and technology. The controlled SWAP test, widely used for state comparison, can be adapted to an efficient and useful test for entanglement of a pure state. Here

Quantum entanglement in helium [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 2011 We compute the entanglement of the ground state and several singlet and triplet excited states of the helium atom using high-quality, state-of-the-art wavefunctions. The behaviour of the entanglement of the helium eigenstates is similar to that observed in some exactly soluble two-electron systems. In particular, the amount of entanglement exhibited by
