In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

The realization of strong interactions between individual photons is a long-standing goal of
both fundamental and technological significance. Scientists have known for over half a …

Chemically made colloidal semiconductor quantum dots have long been proposed as
scalable and color-tunable single emitters in quantum optics, but they have typically suffered …

A central goal within quantum optics is to realize efficient, controlled interactions between
photons and atomic media. A fundamental limit in nearly all applications based on such …

Distributed quantum networks will allow users to perform tasks and to interact in ways which
are not possible with present-day technology. Their implementation is a key challenge for …

Isolating single molecules in the solid state has allowed fundamental experiments in basic
and applied sciences. When cooled down to liquid helium temperature, certain molecules …

Most mode-locking techniques introduced in the past, focused mainly on increasing the
spectral bandwidth to achieve ultrashort, sub-picosecond-long coherent light pulses. By …

An atom in open space can be detected by means of resonant absorption and reemission of
electromagnetic waves, known as resonance fluorescence, which is a fundamental …

The integration of nanophotonics and atomic physics has been a long-sought goal that
would open new frontiers for optical physics, including novel quantum transport and many …

We demonstrate a quantum nanophotonics platform based on germanium-vacancy (GeV)
color centers in fiber-coupled diamond nanophotonic waveguides. We show that GeV …
