We propose a quantum-Hall interferometer that integrates an electron-hole entangler with an analyzer working as an entanglement witness by implementing a multi-rail encoding. The witness has the ability to discriminate (and quantify) spatial-mode and occupancy entanglement. This represents a feasible alternative to limited approaches based on the violation of Bell-like inequalities.

It is found that all entangled pure states, but not all mixed ones, can be detected with only two measurements, except the maximally entangled states, which require three measurements.

Proposal for production and detection of entangled electron-hole pairs in a degenerate electron gas.
We demonstrate theoretically that the shot noise produced by a tunnel barrier in a two-channel conductor violates a Bell inequality. The nonlocality is shown to originate from entangled electron-hole
Characterizing electron entanglement in multiterminal mesoscopic conductors
We show that current correlations at the exit ports of a beam splitter can be used to detect electronic entanglement for a fairly general input state. This includes the situation where electron pairs
Electronic entanglement via quantum Hall interferometry in analogy to an optical method
We present an interferometric scheme producing orbital entanglement in a quantum Hall system upon electron-hole pair emission via tunneling. The proposed setup is an electronic version of the optical

We show that multimode entanglement of electrons in a mesoscopic conductor can be detected by a measurement of the zero-frequency current correlations in an electronic Hong-Ou-Mandel interferometer.
Orbital entanglement and violation of Bell inequalities in mesoscopic conductors.

Lower bound for electron spin entanglement from beam splitter current correlations.
A lower bound for the entanglement of formation of pairs of electron spins injected into a mesoscopic conductor is determined in terms of experimentally accessible quantities, the zero-frequency current correlators after transmission through an electronic beam splitter and can be used to gain information about the entangling from experiment.
Quantitative entanglement witnesses of Isotropic- and Werner-class via local measurements
Quantitative entanglement witnesses allow one to bound the entanglement present in a system by acquiring a single expectation value. In this paper we analyze a special class of such observables which

The quantum-mechanical uncertainty in the position of a particle or the time of its emission is shown to produce observable effects that are inconsistent with any local hidden-variable theory. A new
Electronic entanglement in the vicinity of a superconductor
Abstract:A weakly biased normal-metal-superconductor junction is considered as a potential device injecting entangled pairs of quasi-particles into a normal-metal lead. The two-particle states arise
