- Title: Multi-photon interference phenomena
- Authors: Adrian J Menssen
- Abstract summary: I show that three-photon interference is governed by four parameters and measure three-photon interference independent of two-photon interference.
I demonstrate that even when the states of the photons are highly distinguishable they can still exhibit strong quantum interference.
I present a new framework to describe multi-photon interference in terms of a graph-theoretical approach.

- Abstract: In this work I demonstrate the interference of three photons, a
generalisation of the famous Hong Ou Mandel (HOM) interference. I show that
three-photon interference is governed by four parameters and measure
three-photon interference independent of two-photon interference. I demonstrate
that even when the states of the photons are highly distinguishable they can
still exhibit strong quantum interference, challenging our intuition formed by
the double slit and HOM interference. This is followed by a demonstration of
four-photon interference, where surprisingly we can still observe a "fringe"
when the involved particles are pairwise orthogonal. To explain these effects,
I present a new framework to describe multi-photon interference in terms of a
graph-theoretical approach, which illustrates the origin of different orders of
multi-photon interference. My work leads to a more general definition of what
we regard as an interference fringe in multi-photon scattering. This study of
multi-photon interference is followed by an interdisciplinary work between
photonics and solid state physics in the newly developing field of topological
photonics. I realise a simulation of the Jackiw-Rossi model as a localised
topological mode in a photonic-crystal analogue of the 2D graphene lattice. I
succeed in the experimental demonstration of a single such excitation and I am
able to study the detailed mode structure for the first time. The mode is a
result of a topological defect and is, as such, protected against errors that
do not change the topology of the system.

Indistinguishable bosons may counter-intuitively bunch less than classical, distinguishable particles.
In this setting, we show indistinguishable photons actually minimize the probability of bunching.

It is assumed that distinguishing information in the preparation, evolution or measurement of a system is sufficient to destroy interference.
For more than three independent quantum particles, distinguishability of the prepared states is not a sufficient condition for multiparticle interference to disappear.
