Correcting Quantum Errors with Entanglement [PDF]

, 2006
We show how entanglement shared between encoder and decoder can simplify the theory of quantum error correction. The entanglement-assisted quantum codes we describe do not require the dual-containing constraint necessary for standard quantum error ...

Experimental localisation of quantum entanglement through monitored classical mediator [PDF]

Quantum, 2021
Quantum entanglement is a form of correlation between quantum particles that cannot be increased via local operations and classical communication.

A quantum router architecture for high-fidelity entanglement flows in quantum networks

npj Quantum Information, 2022
The past decade has seen tremendous progress in experimentally realizing the building blocks of quantum repeaters. Repeater architectures with multiplexed quantum memories have been proposed to increase entanglement distribution rates, but an open ...

Quantum Entanglement and Communication Complexity [PDF]

, 1997
We consider a variation of the multi-party communication complexity scenario where the parties are supplied with an extra resource: particles in an entangled quantum state.

How discord underlies the noise resilience of quantum illumination

New Journal of Physics, 2016
The benefits of entanglement can outlast entanglement itself. In quantum illumination, entanglement is employed to better detect reflecting objects in environments so noisy that all entanglement is destroyed.

Entanglement and the Quantum Brachistochrone Problem [PDF]

, 2007
Entanglement is closely related to some fundamental features of the dynamics of composite quantum systems: quantum entanglement enhances the "speed" of evolution of certain quantum states, as measured by the time required to reach an orthogonal state ...

Entanglement purification on quantum networks

Physical Review Research, 2023
We present an approach to entanglement purification on complex quantum network architectures, that is, how a quantum network built from repeaters with limited processing fidelity can purify and distribute entanglement between users.

Detecting quantum entanglement

Theoretical Computer Science, 2002
We review the criteria for separability and quantum entanglement, both in a bipartite as well as a multipartite setting. We discuss Bell inequalities, entanglement witnesses, entropic inequalities, bound entanglement and several features of multipartite entanglement.

Quantum Entanglement

New Scientist
This condensed study extends the T-helison formalism (H²) operator framework to address bipartite and multipartite quantum entanglement. In H², an entangled system is uniquely modelled as a single wave-fractal object characterized by an inseparable spiral topology. A key innovation lies in the replacement of GRW/CSL-type stochastic collapse mechanisms
