Transitions in Entanglement Complexity in Random Circuits [PDF]

open access: yesQuantum, 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.

Quantum Entanglement

open access: yesRevista de Ciência Elementar, 2023
The causes and consequences of the properties of a particle and a wave are presented, during the passage of a quantum of space-matter of an electron, a photon, through one and two slits.

Topologically protected quantum entanglement emitters

open access: yesNature 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 ...

Detecting a Target With Quantum Entanglement [PDF]

open access: yesIEEE 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.

Cost of quantum entanglement simplified [PDF]

open access: yesPhysical Review Letters, 2020
Quantum entanglement is a key physical resource in quantum information processing that allows for performing basic quantum tasks such as teleportation and quantum key distribution, which are impossible in the classical world.

The Effect of Quantum Noise on Multipartite Entanglement from a Cascaded Parametric Amplifier

open access: yesPhotonics, 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 ...

Cloning of Quantum Entanglement [PDF]

open access: yesPhysical 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 ...

Generation of Three-Mode Entanglement Based on Parametric Amplifiers Using Quantum Entanglement Swapping

open access: yesPhotonics, 2022
Quantum entanglement swapping is one of the most promising quantum techniques to create or manipulate large-scale multi-mode entanglement between two distant quantum entangled systems.

Improving cold-atom sensors with quantum entanglement: Prospects and challenges

open access: yes, 2021
Quantum entanglement has been generated and verified in cold-atom experiments and used to make atom-interferometric measurements below the shot-noise limit.
