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…
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…
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…
First- and second-order quantum phase transitions in the long-range unfrustrated antiferromagnetic Ising chain
VÃctor Herráiz-López, Sebastián Roca-Jerat, Manuel Gallego +4
We study the ground-state phase diagram of an unfrustrated antiferromagnetic Ising chain with longitudinal and transverse fields in the full range of interactions: from all-to-all…
Qudit Machine Learning
Sebastián Roca-Jerat, Juan Román-Roche, David Zueco
We present a comprehensive investigation into the learning capabilities of a simple d-level system (qudit). Our study is specialized for classification tasks using real-world datab…
