Strontium optical lattice clocks have the potential to simultaneously interrogate millions of
atoms with a high spectroscopic quality factor of 4× 1017. Previously, atomic interactions …

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

Since Dicke's seminal paper on coherence in spontaneous radiation by atomic ensembles,
superradiance has been extensively studied. Subradiance, on the contrary, has remained …

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 …

We consider quantum metrology in noisy environments, where the effect of noise and
decoherence limits the achievable gain in precision by quantum entanglement. We show …

Quantum metrology pursues the physical realization of higher‐precision measurements to
physical quantities than the classically achievable limit by exploiting quantum features, such …

Critical metrology relies on the precise preparation of a system in its ground state near a
quantum phase transition point where quantum correlations get very strong. Typically, this …

The control and manipulation of quantum-entangled states is crucial for the development of
quantum technologies. A promising route is to couple solid-state quantum emitters through …

This paper provides a comprehensive review of quantum spin sensing with a focus on the
nitrogen vacancy (NV) center in diamond. Beginning with the discovery of optically detected …

Ordered atomic arrays with subwavelength spacing have emerged as an efficient and
versatile light-matter interface, where collective interactions give rise to sets of super-and …
