Abstract

A free-space interferometer constructed from four polarizing beam splitters is examined. Two non-orthogonal linear polarizations of heavily attenuated pulses of mode-locked laser light formed the states to discriminated. On the average, there are 0.1 photons per pulse, ensuring that the probability of two photons in the system at any one time was 1 in 200. The recombined light emerging from the interferometer is analyzed using a half-waveplate and a polarizing beam splitter.
