2. : Measuring Quantum Coherence with Entanglement

Auf dieser Internetseite (http://quantumcorrelations.weebly.com), mit und auch von "Gerardo Adesso", habe ich ein schönes Papier gefunden, was anschaulich die Arbeit vermittelt!

586. WE-Heraeus-Seminar “Quantum Correlations beyond Entanglement”, Bad Honnef, Germany 2015

[kleiner Auszug]


Summary
Discord can be quantified by the minimum entanglement created with an apparatus during a premeasurement
Coherence can be quantified by the maximum entanglement created by incoherent operations
--- Discord can be interpreted and quantified in terms of bipartite coherence minimized over all local bases for subsystem

1. : How Spacetime is built by Quantum Entanglement

[ Along the outside of the figure, individual particles (dots) become entangled with each other. These entangled pairs then become entangled with other pairs. As more particles become entangled, the three-dimensional structure of space-time emerges. ]
