Sample Experiments – Single Photon Interference

Interference is generally considered to be a wave phenomenon. Curiously it also works with single quantum objects. Use the quED-MI Michelson Interferometer add-on together with the quED to show that this is the case:

With the motorised version of the quED-MI, the quCR will plot the coincidence count rates in dependence of the optical path length differences.

What else can be deduced from that? Where does the envelope come frome? What is the distance between the fringes? How can we be sure that single photons have produced this result?

What do you need?

  • 1 x quED (high rate version advised)
  • 1 x quED-MI (for optimal resolution use motorised version)
