Mediator assisted cooling in quantum annealing
M. Pino, Juan José García-Ripoll
We show a significant reduction of errors for an architecture of quantum annealers (QA) where bosonic modes mediate the interaction between qubits. These systems have a large redun…

Quantum annealing in spin-boson model: from a perturbative to a ultrastrong mediated coupling
Manuel Pino, Juan José García-Ripoll
We study a quantum annealer where bosons mediate the Ising-type interactions between qubits. We compare the efficiency of ground state preparation for direct and mediated couplings…
