Generating spatially entangled itinerant photons with waveguide quantum electrodynamics. [PDF]
Sci Adv, 2020 We experimentally demonstrate a new method of generating entangled itinerant photons using waveguide quantum electrodynamics. Realizing a fully connected network of quantum processors requires the ability to distribute quantum entanglement.

Quantum electrodynamics at room temperature coupling a single vibrating molecule with a plasmonic nanocavity. [PDF]
Nat Commun, 2019 Interactions between a single emitter and cavity provide the archetypical system for fundamental quantum electrodynamics. Here we show that a single molecule of Atto647 aligned using DNA origami interacts coherently with a sub-wavelength plasmonic ...

On-demand directional microwave photon emission using waveguide quantum electrodynamics [PDF]
Nature Physics, 2022 Routing quantum information between non-local computational nodes is a foundation for extensible networks of quantum processors. Quantum information transfer between arbitrary nodes is generally mediated either by photons that propagate between them or ...

Coherent control of a multi-qubit dark state in waveguide quantum electrodynamics [PDF]
Nature Physics, 2021 Superconducting qubits in a waveguide have long-range interactions mediated by photons that cause the emergence of collective states. Destructive interference between the qubits decouples the collective dark states from the waveguide environment.
