For any light beam it is normal to characterize the coherence length and time. This is done by measuring the ability light to interfere with itself.
Does it make sense to talk about the coherence of a single photon beam, such as the one used in the double slit experiment? Can a single photon beam be incoherent? I imagine this could be tested using a mach-zehnder interferometer.
