not hard, I do that using a small very dim light in a garage at night 
and detect single photons with a photomultiplier tube with a pin hole 
and pointed at a darker place.

so I use a source, and block all of the photons except one at a time, 
and yes the time is variable.

so the pmt puts out a string of single pulses as each photon hit the face.

haven't you guys done this ?
