The ability of a few-photon light field to impart an appreciable phase shift on another light
field is critical for many quantum information applications,. A recently proposed paradigm for …

The exceptionally large polarizability of highly excited Rydberg atoms—six orders of
magnitude higher than ground-state atoms—makes them of great interest in fields such as …

Recent demonstrations of light-matter interactions with atoms and molecules confined to
hollow waveguides offer great promise for ultralow-light-level applications. The use of …

We demonstrate 25% all-optical modulation with< 20 photons, ie, a few attojoules of energy,
using nondegenerate two-photon absorption in rubidium atoms confined to a hollow-core …

Atomic spectroscopy is a well‐established, integral part of the physicist's toolbox with an
extremely broad range of applications ranging from astronomy to single atom quantum …

Organic coatings have been widely used in atomic physics during the last 50 years because
of their mechanical properties, allowing preservation of atomic spins after collisions …

Alkali-filled hollow-core fibers are a promising medium for investigating light–matter
interactions, especially at the single-photon level, due to the tight confinement of light and …

Strong cross-Kerr nonlinearities have been long sought after for quantum information
applications. Recent work has shown that they are intrinsically unreliable in traveling-wave …

The generation of large multiphoton quantum states—for applications in computing,
metrology and simulation—requires a network of high-efficiency quantum memories capable …

We present Rb vapor transport through micro-scale capillaries on the impact of temperature
and capillary inner diameters within the limits of the Knudsen number K n≫ 1⁠. Daily …
