This Colloquium describes a new paradigm for creating strong quantum interactions of light
and matter by way of single atoms and photons in nanoscopic lattices. Beyond the …

Quantum-enhanced measurements exploit quantum mechanical effects for increasing the
sensitivity of measurements of certain physical parameters and have great potential for both …

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

An array of radiatively coupled emitters provides a platform for generating, storing and
manipulating quantum light. However, the simultaneous positioning and tuning of several …

Universal quantum computation on decoherence-free subspaces and subsystems (DFSs) is
examined with particular emphasis on using only physically relevant interactions. A …

Decoherence is the phenomenon of non-unitary dynamics that arises as a consequence of
coupling between a system and its environment. It has important harmful implications for …

An atom that couples to two distinct leaky optical cavities is driven by an external optical
white noise field. We describe how entanglement between the light fields sustained by two …

We suggest a protocol for perfect quantum communication through spin-chain channels. By
combining a dual-rail encoding with measurements only at the receiving end, we can get …

We study open quantum systems whose evolution is governed by a master equation of
Kossakowski-Gorini-Sudarshan-Lindblad type and give a characterization of the convex set …

The interaction of quantum emitters with one-dimensional photon-like reservoirs induces
strong and long-range dissipative couplings that give rise to the emergence of the so-called …
