1. A system for quantum information processing comprising:
a light source configured to provide a beam of entangled photons;
a detector;
at least one spatial light modulator (SLM) comprising a plurality of discrete pixels and configured to select one or more of said plurality of discrete pixels to generate a resultant beam from said beam of entangled photons; and
at least one optical lens configured to project the resultant beam onto said detector, wherein said at least one SLM is configured to shape a waveform of said beam of entangled photons, wherein shaping said waveform of said beam of entangled photons comprises encoding quantum information onto said beam of entangled photons,
wherein said at least one SLM comprises a first SLM and a second SLM, wherein said at least one optical lens comprises a first optical lens and a second optical lens,
wherein said first optical lens is configured to perform an optical Fourier transform and said first SLM is configured to perform a spatial filter selecting Fourier modes,
wherein a difference between respective measurements in at least two different optical planes is used to reconstruct a property of a joint distribution function,
wherein said at least one optical lens magnifies said beam, so that a beam feature originally separated by no more than one pixel is magnified to be spread out over more than one pixel.
