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…
Multi-emitter oscillating bound states in Waveguide QED
Sergi Terradas-Briansó, Carlos A. González-Gutiérrez, Iván Huarte +2
Waveguide quantum electrodynamics platforms have emerged as promising candidates for exploring and implementing non-Markovian quantum phenomena. In this work, we investigate the fo…
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…
Accelerating Quantum Monte Carlo Calculations with Set-Equivariant Architectures and Transfer Learning
Manuel Gallego, Sebastián Roca-Jerat, David Zueco +1
Machine-learning (ML) ansätze have greatly expanded the accuracy and reach of variational quantum Monte Carlo (QMC) calculations, in particular when exploring the manifold quantum…
Strong spin-magnon coupling in a van der Waals magnet with tunable chiral symmetry
D. GarcÃa-Pons, J. Pérez-Bailón, C. Boix-Constant +6
Quantum technologies require platforms that can coherently interface qubits with bosonic excitations. Photons have traditionally played this role in cavity quantum electrodynamics,…
Waveguide quantum electrodynamics at the onset of spin-spin correlations
Sebastián Roca-Jerat, Marcos RubÃn-Osanz, Mark D. Jenkins +4
We explore the competition between light-mediated and intrinsic matter-matter interactions in waveguide quantum electrodynamics. For this, we couple a superconducting transmission…
