Single-Particle Interference Can Witness Bipartite Entanglement — •Torsten Scholak1, Florian Mintert2,3, and Cord A. Müller11Physikalisches Institut, Universität Bayreuth, 95440 Bayreuth, Germany — 2Max-Planck-Institut für Physik Komplexer Systeme, Nöthnitzerstraße 38, 01187 Dresden, Germany — 3Physikalisches Institut, Albert-Ludwigs-Universität Freiburg, 79104 Freiburg, Germany

We propose to realize entanglement witnesses in terms of the interference pattern of a single quantum probe [1]. After giving a conceptional recipe, we discuss possible realizations both with electrons in mesoscopic Aharonov-Bohm rings and with photons in standard Young's double-slit or coherent-backscattering interferometers.
