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…

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 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…

Strong spin-magnon coupling in a van der Waals magnet with tunable chiral symmetry

D. García-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,…

Mumax3-cQED: an extension of Mumax3 to simulate magnon-photon interactions in cavity QED

Sergio Martínez-Losa del Rincón, Juan Román-Roche, Andrés Martín-Megino +2

We present an extension of the well-known micromagnetic package Mumax3 to simulate magnon-polaritons in realistic magnetic materials and nanostructures. Mumax3-cQED leverages the f…
