Superinductor-based ultrastrong coupling in a superconducting circuit
Alba Torras-Coloma, Luca Cozzolino, Ariadna Gómez-del-Pulgar-MartÃnez +2
We present an ultrastrong superinductor-based coupling consisting of a flux qubit galvanically coupled to a resonator. The coupling inductor is fabricated in granular Aluminum, a s…

Cosmic muon flux attenuation methods for superconducting qubit experiments
Elia Bertoldo, Victor Pérez Sánchez, Maria MartÃnez +3
We propose and demonstrate two practical mitigation methods to attenuate the cosmic muon flux, compatible with experiments involving superconducting qubits: shallow underground sit…
