- Abstract summary: Complex behaviour is predicted for filter bandwidths approaching the emitter linewidth.
We probe this regime using a Purcell-enhanced quantum dot in both weak and strong excitation limits.
Our results verify that strong antibunching and a sub-natural linewidth cannot simultaneously be observed.

- Abstract: Spectral filtering of resonance fluorescence is widely employed to improve
single photon purity and indistinguishability by removing unwanted backgrounds.
For filter bandwidths approaching the emitter linewidth, complex behaviour is
predicted due to preferential transmission of components with differing photon
statistics. We probe this regime using a Purcell-enhanced quantum dot in both
weak and strong excitation limits, finding excellent agreement with an extended
sensor theory model. By changing only the filter width, the photon statistics
can be transformed between antibunched, bunched, or Poissonian. Our results
verify that strong antibunching and a sub-natural linewidth cannot
simultaneously be observed, providing new insight into the nature of coherent
scattering.

Multi-photon interference is at the heart of photonic quantum technologies.
Here, we experimentally demonstrate that detection can be implemented with a temporal resolution sufficient to interfere photons detuned on the scales necessary for cavity-based integrated photon sources.
We show how time-resolved detection of non-ideal photons can be used to improve the fidelity of an entangling operation and to mitigate the reduction of computational complexity in boson sampling experiments.

We investigate the combined effects of spectral and photon number impurity on the measured Hong--Ou--Mandel interference visibility of parametric photon sources.
We find that for any degree of spectral impurity, increasing the photon generation rate necessarily decreases the interference visibility.
While tight spectral filtering can be used to enforce spectral purity and increased interference visibility at low powers, we find that the induced photon number impurity results in a decreasing interference visibility and heralding efficiency with pump power.
