Nanophotonics offers opportunities for engineering and exploiting the quantum properties of
light by integrating quantum emitters into nanostructures, and offering reliable paths to …

Structured waves are ubiquitous for all areas of wave physics, both classical and quantum,
where the wavefields are inhomogeneous and cannot be approximated by a single plane …

We demonstrate a superconducting artificial atom with strong unidirectional coupling to a
microwave photonic waveguide. Our artificial atom is realized by coupling a transmon qubit …

Superconducting qubits in a waveguide have long-range interactions mediated by photons
that cause the emergence of collective states. Destructive interference between the qubits …

We study the generation of quantum entanglement between two giant atoms coupled to a
one-dimensional waveguide. Since each giant atom interacts with the waveguide at two …

A central challenge in the emerging field of free-electron quantum optics is to achieve strong
quantum interaction and single-photon nonlinearity between a flying free electron and a …

The quantum battery (QB) makes use of quantum effects to store and supply energy, which
may outperform its classical counterpart. However, there are two challenges in this field. One …

Metal nanomaterials have emerged as compelling candidates for ultrafast photonics
applications, owing to their outstanding saturable absorption properties induced by surface …

We study chiral and nonreciprocal single-photon scattering in a chiral-giant-molecule
waveguide-QED system. Here, the giant molecule consists of two coupled giant atoms …

Engineering the electromagnetic environment of a quantum emitter gives rise to a plethora
of exotic light-matter interactions. In particular, photonic lattices can seed long-lived atom …
