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…

Spin-1 Haldane phase in a chain of Rydberg atoms
J. Mögerle, K. Brechtelsbauer, A. T. Gea-Caballero +7
We present a protocol to implement a spin-1 chain in Rydberg systems using three Rydberg states close to a Förster resonance. In addition to dipole-dipole interactions, strong van…

Continuous variable measurement-device-independent quantum certification
B. L. Larsen, A. A. E. Hajomer, P. Abiuso +5
Secure and reliable certification of quantum resources is a fundamental challenge in the advancement of next-generation quantum technologies, particularly as devices become more co…
