Ultrastrong Coupling and Coherent Dynamics in a Gate-Tunable Transmon Qubit
I. Casal Iglesias, F. J. Matute-Cañadas, G. O. Steffensen +10
Ultrastrong light-matter coupling (USC) gives access to exotic quantum phenomena and promises faster quantum gates, yet coherent time-domain control in this regime remains largely…

Polariton-polariton coherent coupling in a molecular spin-superconductor chip
Carolina del RÃo, Marcos RubÃn-Osanz, David Rodriguez +12
The ability to establish coherent communication channels is key for scaling up quantum devices. Here, we engineer interactions between distant polaritons, hybrid spin-photon excita…

Optimizing magnetic coupling in lumped element superconducting resonators for molecular spin qubits
Marcos RubÃn-Osanz, David Rodriguez, Ignacio Gimeno +18
We engineer lumped-element superconducting resonators that maximize magnetic coupling to molecular spin qubits, achieving record single-spin couplings up to kHz and collectiv…
