Optical interferometry with single photons and nonclassical light

Having discussed in the previous chapters many different aspects of single photons and nonclassical light, we are now ready to discuss interferometry with single photons. We first discuss traditional interferometers and their performance if classical light beams are replaced by quantum fields.

The earliest interferometer is the Young’s double slit interferometer. Young’s work on interference confirmed the wave nature of light and was a turning point in optics. A complete description of Young’s double slit is more complicated as it involves the propagation of wavefronts through the slits and hence we will take it up in Chapter 8. Michelson designed an interferometer which he ...
