This study demonstrates what kind of quantum features can be seen at low temperatures in the motion of comparatively heavy atoms. An anharmonic double oscillator is taken here as an example to compare classical, semi-classical and quantum motion. In the two latter cases a classically simple motion may become very complicated due to a combined effect of the uncertainty and the anharmonicity. A computationally efficient way to include the Heisenberg uncertainty into classical molecular dynamics is introduced.

We show that the time evolution of the wave function of a quantum mechanical many particle system can be implemented very efficiently on a quantum computer. The computational cost of such a simulation is comparable to the cost of a conventional simulation of the corresponding classical system. Ultim
This paper describes a parallel algorithm for quantum dynamics simulations of three body Coulomb problems. The algorithm has been implemented on a SIMD (single instruction multiple data) computer (MasPar MPI). The algorithm employs the finite-difference and split operator (FD-SPO) method and variabl
