- Abstract: We consider the time delay of interfering single photons oppositely traveling
in the Kerr metric of a rotating massive object. Classically, the time delay
shows up as a phase difference between coherent sources of light. In quantum
mechanics, the loss in visibility due to the indistinguishability of
interfering photons is directly related to the time delay. We can thus observe
the Kerr frame-dragging effect using the Hong-Ou-Mandel (HOM) dip, a purely
quantum mechanical effect. By Einstein's equivalence principle, we can
analogously consider a rotating turntable to simulate the Kerr metric. We look
at the feasibility of such an experiment using optical fibre, and note a
cancellation in the second-order dispersion but a direction-dependent
difference in group velocity. However, for the chosen experimental parameters,
we can effectively assume light propagating through a vacuum.

Indistinguishable bosons may counter-intuitively bunch less than classical, distinguishable particles.
In this setting, we show indistinguishable photons actually minimize the probability of bunching.
The observation of these counter-intuitive phenomena open news perspective in devising more efficient ways of routing photons.

Two-photon interference (TPI) is a fundamental phenomenon in quantum optics.
We report a simultaneous observation of quantum and classical TPI of single photons with ultralong coherence time.
We conclude that quantum TPI with a stream of single photons is equivalent to classical TPI.

We show that the single-photon nonlinearity vanishes with the number of emitters.
The mechanism behind this behavior is the quantum Zeno effect, manifested in the slowdown of the photon-controlled dynamics.

experiments of quantum mechanics [0.0]
This paper examines the arguments that relate the photon momenta to the "which path" question at the heart of quantum mechanics.
We show that the linear momenta imparted to apertures or mirrors, or the angular momenta picked up by strategically placed wave-plates, could lead to an identification of the photon's path only at the expense of destroying the corresponding interference effects.

Boson bunching is one of the most remarkable features of quantum physics.
We disproof the link between indistinguishability and bunching by exploiting a recent finding in the theory of matrix permanents.
This unexpected behavior questions our understanding of multiparticle interference in the grey zone between indistinguishable bosons and classical particles.

Quantum asymmetry is a physical resource which coincides with the amount of coherence between the eigenspaces of a generator.
We show that the asymmetry may emphincrease as a result of a emphdecrease of coherence inside a degenerate subspace.

We demonstrate how quantum time dilation manifests in a spontaneous emission process.
The resulting emission rate differs when compared to the emission rate of an atom prepared in a mixture of momentum wave packets.
We argue that spectroscopic experiments offer a technologically feasible platform to explore the effects of quantum time dilation.
