Fast, high-fidelity Transmon readout with intrinsic Purcell protection via nonperturbative cross-Kerr coupling
Guillaume Beaulieu, Jun-Zhe Chen, Marco Scigliuzzo +5
Dispersive readout of superconducting qubits relies on a transverse capacitive coupling that hybridizes the qubit with the readout resonator, subjecting the qubit to Purcell decay…
Superstrong Dynamics and Directional Emission of a Giant Atom in a Structured Bath
Vincent Jouanny, Léo Peyruchat, Marco Scigliuzzo +8
Quantum emitters coupled to waveguides with nonlinear dispersion show rich quantum dynamics with the promise of implementing non-trivial non-Markovian quantum models. Recent advanc…
Emergent cavity-QED dynamics along the edge of a photonic lattice
Enrico Di Benedetto, Xuejian Sun, Marcel A. Pinto +6
We investigate qubits coupled to the boundary of a two dimensional photonic lattice that supports dispersionless edge modes, unlike conventional edge modes that sustain propagating…
