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 …

For more than a century, the resolution of focusing light microscopy has been limited by
diffraction to 180 nm in the focal plane and to 500 nm along the optic axis. Recently …

Photon emission is the hallmark of light-matter interaction and the foundation of photonic
quantum science, enabling advanced sources for quantum communication and computing …

Many important energy-transfer and optical processes, in both biological and artificial
systems, depend crucially on excitonic coupling that spans several chromophores,,,,,,,,. Such …

Quantum cooperativity is evident in light-matter platforms where quantum-emitter ensembles
are interfaced with confined optical modes and are coupled via the ubiquitous …

Ways to characterize and control excited states at the single-molecule and atomic levels are
needed to exploit excitation-triggered energy-conversion processes. Here, we present a …

We report the observation of subradiance in dense ensembles of cold Rb 87 atoms
operating near Dicke's regime of a large number of atoms in a volume with dimensions …

Rabi nutations of a single nuclear spin in a solid have been observed. The experiments
were carried out on a single electron and a single C 13 nuclear spin of a single nitrogen …

Optical studies have revealed that, after binding, virions move laterally on the plasma
membrane, but the complexity of the cellular environment and the drawbacks of …

Coherent coupling between single quantum objects is at the very heart of modern quantum
physics. When the coupling is strong enough to prevail over decoherence, it can be used to …
