Quantum oscillations without quantum coherence
V. V. Dobrovitski, H. A. De Raedt, M. I. Katsnelson +1
We study numerically the damping of quantum oscillations and the increase of entropy with time in model spin systems decohered by a spin bath. In some experimentally relevant cases…
Programming physical realizations of quantum computers
Hans De Raedt, Kristel Michielsen, Anthony Hams +2
We study effects of the physical realization of quantum computers on their logical operation. Through simulation of physical models of quantum computer hardware, we analyze the dif…
Quantum Monte Carlo Method for Attractive Coulomb Potentials
J. S. Kole, H. De Raedt
Starting from an exact lower bound on the imaginary-time propagator, we present a Path-Integral Quantum Monte Carlo method that can handle singular attractive potentials. We illust…
