- Abstract summary: Single molecules in solid-state matrices have been proposed as sources of single-photon Fock states back 20 years ago.
Main challenges as of today for their application in photonic quantum technologies are the optimization of light extraction and the on-demand emission of indistinguishable photons.
We here present Hong-Ou-Mandel experiments with photons emitted by a single molecule of dibenzoterrylene in an anthracene nanocrystal at 3 K, under continuous wave and also pulsed excitation.

- Abstract: Single molecules in solid-state matrices have been proposed as sources of
single-photon Fock states back 20 years ago. Their success in quantum optics
and in many other research fields stems from the simple recipes used in the
preparation of samples, with hundreds of nominally identical and isolated
molecules. Main challenges as of today for their application in photonic
quantum technologies are the optimization of light extraction and the on-demand
emission of indistinguishable photons. We here present Hong-Ou-Mandel
experiments with photons emitted by a single molecule of dibenzoterrylene in an
anthracene nanocrystal at 3 K, under continuous wave and also pulsed
excitation. A detailed theoretical model is applied, which relies on
independent measurements for most experimental parameters, hence allowing for
an analysis of the different contributions to the two-photon interference
visibility, from residual dephasing to spectral filtering.

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.
