Quantum optimal control, a toolbox for devising and implementing the shapes of external
fields that accomplish given tasks in the operation of a quantum device in the best way …

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 …

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 …

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

Engineering light-matter interactions at the quantum level has been central to the pursuit of
quantum optics for decades. Traditionally, this has been done by coupling emitters, typically …

Quantum emitters in the presence of an electromagnetic reservoir with varying density of
states, or structure, can undergo a rich set of dynamical behavior. In particular, the reservoir …

Virtual photons can mediate interaction between atoms, resulting in an energy shift known
as a collective Lamb shift. Observing the collective Lamb shift is challenging, since it can be …

Entanglement is a key resource in quantum computing and other prospective technologies.
Multidimensional photonic graph states, such as cluster states, have a special entanglement …

Superconducting quantum circuits are among the most promising solutions for the
development of scalable quantum computers. Built with sizes that range from microns to tens …

We investigate the two-photon scattering processes in a one-dimensional waveguide
coupled to either a two-level or three-level giant atom. By manipulating the accumulated …
