Query: Photon indistinguishability measurements under pulsed and continuous
  excitation   The indistinguishability of successively generated photons from a single
quantum emitter is most commonly measured using two-photon interference at a
beam splitter. Whilst for sources excited in the pulsed regime the measured
bunching of photons reflects the full wavepacket indistinguishability of the
emitted photons, for continuous wave (cw) excitation the inevitable dependence
on detector timing resolution and driving strength obscures the underlying
photon interference process. Here we derive a method to extract the photon
indistinguishability from cw measurements by considering the relevant
correlation functions. The equivalence of both methods is experimentally
verified through comparison of cw and pulsed excitation of an archetypal source
of photons, a single molecule.
