We propose an experimental test of Bell's inequality using entangled photon holes rather than entangled photon pairs. The experiment involves feeding entangled photon holes into a time-bin based two-photon interferometer.
We describe how spectrally multimode, polarization-entangled photons simultaneously teleport quantum information encoded into the spectral and polarization degrees of freedom of a single photon using sum frequency generation to implement a Bell-state measurement.
Quantum teleportation is analyzed in the context of multi-mode interference effects. The teleportation fidelity depends on the spectral relationship between the entangled photons and on the spectral overlap between the photons in the Bell-state measurement.
Polarisation-entangled photon pairs are generated from single InAs quantum dots. This is achieved by restoring the degeneracy of the exciton level with an in-plane magnetic field or by careful selection of the dot.
