LINKS AND QUANTUM ENTANGLEMENT [PDF]
Proceedings of the Conference in Honour of Murray Gell-Mann's 80th Birthday, 2010 We discuss the analogy between topological entanglement and quantum entanglement, particularly for tripartite quantum systems. We illustrate our approach by first discussing two clearly (topologically) inequivalent systems of three-ring links: The Borromean rings, in which the removal of any one link leaves the remaining two non-linked (or, by analogy,

QUANTUMNESS OF CORRELATIONS AND ENTANGLEMENT [PDF]
International Journal of Quantum Information, 2011 Generalized measurement schemes on one part of bipartite states, which would leave the set of all separable states insensitive are explored here to understand quantumness of correlations in a more general perspective. This is done by employing linear maps associated with generalized projective measurements.

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.

Witnessing light-driven entanglement using time-resolved resonant inelastic X-ray scattering
Nature Communications, 2023 Characterizing and controlling entanglement in quantum materials is crucial for the development of next-generation quantum technologies. However, defining a quantifiable figure of merit for entanglement in macroscopic solids is theoretically and ...

Sensors, 2022 A quantum illumination radar uses quantum entanglement to enhance photodetection sensitivity. The entanglement is quickly destroyed by the decoherence in an environment, although the sensitivity enhancement could survive thanks to quantum correlations ...

Static Entanglement Analysis of Quantum Programs [PDF]
arXiv, 2023 Quantum entanglement plays a crucial role in quantum computing. Entangling information has important implications for understanding the behavior of quantum programs and avoiding entanglement-induced errors. Entanglement analysis is a static code analysis technique that determines which qubit may entangle with another qubit and establishes an ...

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,

Quantum Entanglement: Spooky Action at a Distance
Quanta, 2020 Quantum entanglement is an important resource in quantum information technologies. Here, we study and characterize in a precise mathematical language some of the weird and nonintuitive features of quantum entanglement.

Maximally entangled state and fully entangled fraction [PDF]
Physical Review A 91, 012310 (2015), 2016 We study maximally entangled states and fully entangled fraction in general d'\otimes d (d'\geq d) systems. Necessary and sufficient conditions for maximally entangled pure and mixed states are presented. As a natural generalization of the usual fully entangled fraction for d\otimes d systems, we define the maximal overlap between a given quantum state
