Polariton-polariton coherent coupling in a molecular spin-superconductor chip
Carolina del Río, Marcos Rubín-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 Rubín-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…
A genetic algorithm to generate maximally orthogonal frames in complex space
Sebastián Roca-Jerat, Juan Román-Roche
A frame is a generalization of a basis of a vector space to a redundant overspanning set whose vectors are linearly dependent. Frames find applications in signal processing and qua…
First- and second-order quantum phase transitions in the long-range unfrustrated antiferromagnetic Ising chain
Víctor 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…
Transformer Wave Function for Quantum Long-Range models
Sebastián Roca-Jerat, Manuel Gallego, Fernando Luis +2
We employ a neural-network architecture based on the Vision Transformer (ViT) architecture to find the ground states of quantum long-range models, specifically the transverse-field…
Waveguide quantum electrodynamics at the onset of spin-spin correlations
Sebastián Roca-Jerat, Marcos Rubín-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…
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…
Circuit Complexity through phase transitions: consequences in quantum state preparation
Sebastián Roca-Jerat, Teresa Sancho-Lorente, Juan Román-Roche +1
In this paper, we analyze the circuit complexity for preparing ground states of quantum many-body systems. In particular, how this complexity grows as the ground state approaches a…
