Entanglement is one of the most intriguing features of quantum mechanics. It describes non-local correlations between quantum objects, and is at the heart of quantum information sciences. Entanglement is rapidly gaining prominence in diverse fields ranging from condensed matter to quantum gravity. Despite this generality, measuring entanglement remains challenging. This is especially true in systems of interacting delocalized particles, for which a direct experimental measurement of spatial…

Spatial entanglement of bosons in optical lattices

This work adopts recently developed approaches for the determination of rigorous lower entanglement bounds from readily accessible measurements and applies them in an experiment of ultracold interacting bosons in optical lattices of ~10(5) sites, constituting the first rigorous experimental large-scale entanglements quantification in a scalable quantum simulator.

Experimental determination of entanglement with a single measurement

A linear optics experiment is reported in which a pure-state entanglement measure is directly observed, namely concurrence, which is measured with a single, local measurement on just one of the photons.

Direct Measurement of Nonlinear Properties of Bipartite Quantum States

This work extracts a nonlocal and a nonlinear quantity, namely the Renyi entropy, from local measurements on two pairs of polarization entangled photons and introduces a “phase marking” technique which allows to select uncorrupted outcomes even with nondeterministic sources of entangled photons.

Physical interactions in quantum many-body systems are typically local: Individual constituents interact mainly with their few nearest neighbors. This locality of interactions is inherited by a decay…

Unbounded growth of entanglement in models of many-body localization.

The significance for proposed atomic experiments is that local measurements will show a large but nonthermal entropy in the many-body localized state, which develops slowly over a diverging time scale as in glassy systems.

It is found that entanglement entropy of the projected Fermi sea state violates the boundary law, with S(2) enhanced by a logarithmic factor, an unusual result for a bosonic wave function reflecting the presence of emergent fermions.

Atomic Hong–Ou–Mandel experiment

Two-particle interference is a fundamental feature of quantum mechanics, and is even less intuitive than wave–particle duality for a single particle. In this duality, classical concepts—wave or…
