Traditional simulated annealing uses thermal fluctuations for convergence in optimization problems. Quantum tunneling provides a different mechanism for moving between states, with the potential for reduced time scales. Thermal and quantum annealing are compared in a model disordered magnet, where the effects of quantum mechanics can be tuned by varying an applied magnetic field. The results indicate that quantum annealing hastens convergence to the optimum state. 
Quantum tunneling vs. thermal effects in experiments on adiabatic quantum computing
Traditional simulated annealing uses thermal fluctuations for convergence in optimization problems. Quantum tunneling provides a different mechanism for moving between states, with the potential for
Thermal, quantum and simulated quantum annealing: analytical comparisons for simple models
We study various annealing dynamics, both classical and quantum, for simple mean-field models and explain how to describe their behavior in the thermodynamic limit in terms of differential equations.
A comparison of classical and quantum annealing dynamics
Simulated annealing and quantum annealing are algorithms for combinatorial optimization problems. The former brings solutions using thermal fluctuations and through classical dynamics, while the
Quantum ferromagnetic annealing
Quantum 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
Residual Energies after Slow Quantum Annealing
The features of residual energy after quantum annealing are investigated. The quantum annealing method exploits quantum fluctuations to find out the ground state of the classical disordered
Theory of Quantum Annealing of an Ising Spin Glass
TLDR
By comparing classical and quantum Monte Carlo annealing protocols on the two-dimensional random Ising model (a prototype spin glass), this work confirms the superiority of quantumAnnealing relative to classical annealed and proposes a theory of quantum annealer based on a cascade of Landau-Zener tunneling events.
Nested quantum annealing correction at finite temperature: p -spin models
Quantum annealing in a real device is necessarily susceptible to errors due to diabatic transitions and thermal noise. Nested quantum annealing correction is a method to suppress errors by using an
Quantum annealing via real-time Schrödinger dynamics
Quantum annealing provides a way to potentially solve optimisation problems faster than its classical counterpart, simulated annealing, but the suitability of this method is still open to debate.

From classical to quantum glass.
TLDR
A rapid decrease in the characteristic relaxation times, large changes in the spectral form of the relaxation, and a depression of the spin-glass transition temperature with the introduction of quantum fluctuations are observed.

TLDR
A detailed analogy with annealing in solids provides a framework for optimization of the properties of very large and complex systems.

TLDR
The magnetic correlations, susceptibility, specific heat, and thermal relaxation in the dipolar-coupled Ising system LiHo_xY_(1-x)F_4.4 is measured to be consistent with a single low-degeneracy ground state with a large gap for excitations.
Bulk Spin-Resonance Quantum Computation
TLDR
A new approach to quantum computing is introduced based on the use of multiple-pulse resonance techniques to manipulate the small deviation from equilibrium of the density matrix of a macroscopic ensemble so that it appears to be the density Matrix of a much lower dimensional pure state.

TLDR
This work has measured the ac magnetic susceptibility of the model dilute dipolar-coupled Ising system LiHo_xY_(1−x)F_4, which displays an ordinary ferromagnetic transition and the more concentrated glass shows history dependence and metastability upon field cooling.

TLDR
The analogy between images and statistical mechanics systems is made and the analogous operation under the posterior distribution yields the maximum a posteriori (MAP) estimate of the image given the degraded observations, creating a highly parallel ``relaxation'' algorithm for MAP estimation.
