Time-bin entanglement of quasi-particles in semiconductor devices

Abstract

We propose a scheme to produce time bin entangled pairs of electrons and holes based on high frequency time-resolved single electron emission from a quantum dot coupled to 1D chiral channels. At first order in the tunneling rate, an electron-hole pair is emitted in a coherent superposition state of different time bins that violates a CHSH inequality. in our scheme entanglement can be detected by means of a Franson interferometer in which the electron and the hole are sent towards different Mach-Zehnder interferometers. An analysis of current cross-correlations allows to detect violations of the CHSH inequality.
