First-principles study of dispersive readout in circuit QED
Angela Riva, Prakritish Gogoi, Nicolas Gheeraert +4
The speed and fidelity of dispersive readout of superconducting qubits should improve by increasing the amplitude of the measurement drive. Experiments show, however, that beyond s…
Expedited Noise Spectroscopy of Transmon Qubits
Bhavesh Gupta, Vismay Joshi, Udit Kandpal +3
There has been tremendous progress in the physical realization of quantum computing hardware in recent times, bringing us closer than ever before to realizing the promise of quantu…
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…
Spontaneous emission of Schrödinger cats in a waveguide at ultrastrong coupling
Nicolas Gheeraert, Soumya Bera, Serge Florens
Josephson circuits provide a realistic physical setup where the light-matter fine structure constant can become of order one, allowing to reach a regime dominated by non-perturbati…
Impact of quantized vibrations on the efficiency of interfacial charge separation in photovoltaic devices
Soumya Bera, Nicolas Gheeraert, Simone Fratini +2
We demonstrate that charge separation at donor-acceptor interfaces is a complex process that is controlled by the combined action of Coulomb binding for electron-hole pairs and par…
