Hybrid quantum annealing via molecular dynamics

Hybrid Quantum Annealing for Clustering Problems

We develop a hybrid type of quantum annealing in which we control temperature and quantum field simultaneously. We study the efficiency of proposed quantum annealing and find a good schedule of changing thermal fluctuation and quantum fluctuation. In this paper, we focus on clustering problems which are important topics in information science and engineering. We obtain the better solution of th...

Hybrid classical-quantum dynamics

A hybrid formalism is proposed for interacting classical and quantum sytems. This formalism is mathematically consistent and reduces to standard classical and quantum mechanics in the case of no interaction. However, in the presence of interaction, the correspondence principle is violated. PACS numbers: 03.65.Bz, 03.65.Sq ∗ Electronic mail: [email protected], [email protected]

Quantum - Classical Molecular Dynamics

We study time integration methods for equations of mixed quantum-classical molecular dynamics in which Newtonian equations of motion and Schrr odinger equations are nonlinearly coupled. Such systems exhibit diierent time scales in the classical and the quantum evolution, and the solutions are typically highly oscillatory. The numerical methods use the exponential of the quantum Hamiltonian whos...

Hybrid molecular-continuum fluid dynamics.

We describe recent developments in the hybrid atomistic/continuum modelling of dense fluids. We discuss the general implementation of mass, momentum and energy transfers between a region described by molecular dynamics and a neighbouring domain described by the Navier-Stokes equations for unsteady continuum fluid flow.
