Quantum-mechanical effects at the macroscopic level were first explored in Josephson-
junction-based superconducting circuits in the 1980s. In recent decades, the emergence of …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

This review describes the emerging field of waveguide quantum electrodynamics concerned
with the interaction of photons propagating in a waveguide with localized quantum emitters …

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 …

The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

Abstract Models of light–matter interactions in quantum electrodynamics typically invoke the
dipole approximation,, in which atoms are treated as point-like objects when compared to …

Photon-photon scattering in vacuum is extremely weak. However, strong effective
interactions between single photons can be realized by employing strong light-matter …

We report dissipative magnon-photon coupling caused by the cavity Lenz effect, where the
magnons in a magnet induce a rf current in the cavity, leading to a cavity backaction that …

Photon-mediated interactions between atoms are of fundamental importance in quantum
optics, quantum simulations, and quantum information processing. The exchange of real …

Routing quantum information between non-local computational nodes is a foundation for
extensible networks of quantum processors. Quantum information transfer between arbitrary …
