- Abstract: The interference of single photons going through a double slit is a
compelling demonstration of the wave and particle nature of light in the same
experiment. Single photons produced by spontaneous parametric down-conversion
can be used for this purpose. However, it is particularly challenging to
implement due to coherency and resolution challenges. In this article, we
present a tabletop laboratory arrangement suitable for the undergraduate
instruction laboratory that overcomes these challenges. The apparatus scans a
single detector to produce a plot showing the interference patterns of single
photons. We include experimental data obtained using this setup demonstrating
double-slit and single-slit interference as well as quantum erasing through the
use of sheet polarizers.

We experimentally demonstrate this effect in a four-photon interferometer, where the interference is nonlocal, in principle.
A joint detection of all four photons identifies a high-visibility interference pattern varying as a function of their collective four-particle phase, a genuine four-body property.

In this work, we demonstrate experimentally that the two-particle coincidence statistics of two bosons can instead be seamlessly tuned to substantial enhancement.
