Accessing electronic entanglement via photo-assisted two-electron tomography
This research developed a photo-assisted two-electron tomography protocol to measure two-particle quantum correlations, specifically entanglement, in electronic systems like quantum Hall edge channels. The method reconstructs the irreducible two-body part of electron coherence from measurable dc currents and noise correlations. This provides a model-independent way to detect interaction-induced entanglement by identifying specific physical signatures.
