Transition from pure-state to mixed-state entanglement by random scattering
J. L. van Velsen, C. W. J. Beenakker
We calculate the effect of polarization-dependent scattering by disorder on the degree of polarization-entanglement of two beams of radiation. Multi-mode detection converts an init…
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…
Scattering theory of plasmon-assisted entanglement transfer and distillation
J. L. van Velsen, J. Tworzydlo, C. W. J. Beenakker
We analyse the quantum mechanical limits to the plasmon-assisted entanglement transfer observed by E. Altewischer, M.P. van Exter, and J.P. Woerdman [Nature, 418, 304 (2002)]. The…
