From quantum reservoirs to quantum extreme learning machines through a nearest-neighbor spin chain with tunable quantum memory
Carlos Ramon-Escandell, Arnau Riera, Marcin Płodzień
Quantum Reservoir Computing (QRC) processes temporal data by retaining a memory of past inputs in the recurrent state of a quantum system, whereas a Quantum Extreme-Learning Machin…

Dressed magnon dynamics in a Bose-Hubbard bath: retardation, pairing, entanglement and two-magnon scattering
Andrés N. Cáliz, Arnau Riera, Enrique Rico +2
We study one- and two-magnon dynamics in a spin- XX chain coupled to a tunable Bose-Hubbard bath. The XX Hamiltonian transports the magnons, while the bath dresses their motio…
