We demonstrate photon-mediated interactions between two individually trapped atoms
coupled to a nanophotonic cavity. Specifically, we observe collective enhancement when …

The collective absorption and emission of light by an ensemble of atoms is at the heart of
many fundamental quantum optical effects and the basis for numerous applications …

In a non-reciprocal optical amplifier, gain depends on whether the light propagates forwards
or backwards through the device. Typically, one requires either the magneto-optical effect …

Interfacing cold atoms with integrated nanophotonic devices could offer new paradigms for
engineering atom-light interactions and provide a potentially scalable route for quantum …

We experimentally investigate the collective radiative decay of a fully inverted ensemble of
two-level atoms for a chiral, ie, propagation direction-dependent light-matter coupling …

We demonstrate an efficient optical guiding technique for coupling cold atoms in the near
field of a planar nanophotonic circuit, and realize large atom-photon coupling to a …

Wavelengths in the telecommunication window (approximately 1.25–1.65 μ m) are ideal for
quantum communication due to low transmission loss in fiber networks. To realize quantum …

We demonstrate efficient interfacing of individually trapped single atoms to a nanofiber
cavity. The cavity is formed by fabricating photonic crystal structures directly on the nanofiber …

In a cavity quantum electrodynamics (QED) system, where atoms coherently interact with
photons in a cavity, the eigenstates of the system are the superposition states of atoms and …

We realize a mechanical analogue of the Dicke model, achieved by coupling the spin of
individual neutral atoms to their quantized motion in an optical trapping potential. The atomic …
