Dephasing of entangled electron-hole pairs in a degenerate electron gas
J. L. van Velsen, M. Kindermann, C. W. J. Beenakker
A tunnel barrier in a degenerate electron gas was recently discovered as a source of entangled electron-hole pairs. Here, we investigate the loss of entanglement by dephasing. We c…

Production and detection of entangled electron-hole pairs in a degenerate electron gas
C. W. J. Beenakker, C. Emary, M. Kindermann +1
We demonstrate theoretically that the shot noise produced by a tunnel barrier in a two-channel conductor violates a Bell inequality. The non-locality is shown to originate from ent…
