- Abstract: Experimental demonstrations of entangled quantum images produced through
parametric downconversion have so far been confined to studying two photon
correlations. Here we show that multiphoton correlations between quantum images
are accessible experimentally and exhibit many new features including being
sensitive to the phase of the bi-photon wavefunction. As a concrete example, we
consider a modification of existing quantum imaging experiments in which the
CCD cameras are moved out of focus, provide detailed analytical predictions for
the resulting 4 photon intereferences, and support these by numerical
simulations. The proposed experiment can also be interpreted as entanglement
swapping: Bob's photons are initially unentangled, but the joint detection of
Alice's photons projects Bob's photons onto an entangled state. The general
approach proposed here can be extended to other quantum optics experiments
involving high dimensional entanglement.
