Programmable directional emitter and receiver of itinerant microwave photons in a waveguide
Nicolas Gheeraert, Shingo Kono, Yasunobu Nakamura
We theoretically demonstrate dynamically selective bidirectional emission and absorption of a single itinerant microwave photon in a waveguide. The proposed device is an artificial…
Multiplexed readout of four qubits in 3D cQED architecture using broadband JPA
Suman Kundu, Nicolas Gheeraert, Sumeru Hazra +4
We propose and demonstrate a frequency-multiplexed readout scheme in 3D cQED architecture. We use four transmon qubits coupled to individual rectangular cavities which are aperture…
Particle Production in Ultra-Strong Coupling Waveguide QED
Nicolas Gheeraert, Xin H. H. Zhang, Théo Sépulcre +4
Understanding large-scale interacting quantum matter requires dealing with the huge number of quanta that are produced by scattering even a few particles against a complex quantum…
A tunable Josephson platform to explore many-body quantum optics in circuit-QED
Javier Puertas Martinez, Sebastien Leger, Nicolas Gheeraert +10
Coupling an isolated emitter to a single mode of the electromagnetic field is now routinely achieved and well understood. Current efforts aim to explore the coherent dynamics of em…
