Computing Expectation Values for Molecular Quantum Dynamics

We compute expectation values for the solution of the nuclear Schrödinger equation. The proposed particle method consists of three steps: sampling of the initial Wigner function, classical transport of the sampling points, weighted phase space summation for the final computation of the expectation values. The Egorov theorem guarantees that the algorithm is second order accurate with respect to ...

Quantum computing applied to calculations of molecular energies: CH2 benchmark.

Quantum computers are appealing for their ability to solve some tasks much faster than their classical counterparts. It was shown in [Aspuru-Guzik et al., Science 309, 1704 (2005)] that they, if available, would be able to perform the full configuration interaction (FCI) energy calculations with a polynomial scaling. This is in contrast to conventional computers where FCI scales exponentially. ...

Computing with Molecules: A New Type of Quantum Molecular Computation

Quantum Computing

uantum computers will utilize nonclassical logic operations to perform numerical calculations that are not feasible on conventional computers. The enhanced capabilities of quantum computers result partly from their expected ability to perform many different calculations simultaneously on a single processor. The Applied Physics Laboratory is developing an optical approach to quantum computing. (

Quantum Computing

This paper gives a glimpse of basic quantum computing concepts, which is an active area of research in today's world. The discussion starts with difference between a quantum computer and a classical one at the bit level, register level, logic gates level and at circuit level. Then, some of the important quantum phenomena such as quantum entanglement and quantum interference are discussed. After...
