Quantum Probability and Infinite Dimensional Analysis, 2010
In the evolution of a quantum system subject to a nonlinear dissipative term of Kostin type the probability amplitudes associated to excited states of the Hamiltonian are damped; this results in a dynamic convergence toward the ground state. In this paper we dicuss how dissipation can replace adiabatic evolution in the search of the ground state of a ...

Scaling Advantage in Approximate Optimization with Quantum Annealing.
Physical Review LettersQuantum annealing is a heuristic optimization algorithm that exploits quantum evolution to find low-energy states. Quantum annealers have scaled up in recent years to tackle increasingly larger and more highly connected discrete optimization and quantum ...

Quantum ferromagnetic annealing
Physica E: Low-dimensional Systems and Nanostructures, 2007Quantum annealing by ferromagnetic interaction is investigated for random-field Ising ferromagnets and Ising spin-glasses, using the Bethe-type mean-field annealing scheme. The fact that there are rooms of choice of the type of quantum fluctuations is a prominent feature in quantum annealing which does not exist in classical simulated annealing ...

Quantum annealing with manufactured spins
Nature, 2011Many interesting but practically intractable problems can be reduced to that of finding the ground state of a system of interacting spins; however, finding such a ground state remains computationally difficult. It is believed that the ground state of some naturally occurring spin systems can be effectively attained through a process called quantum ...
