Eigenstate preparation is ubiquitous in quantum computing, and a standard approach for generating the lowest-energy states of given system by employing adiabatic state (ASP). In present work, we investigate variational method determining optimal scheduling procedure within context ASP. absence error correction, running device any meaningful amount time causes to become susceptible loss relevant...

Interaction and correlation effects in quantum dots play a fundamental role in defining both their equilibrium and transport properties. Numerical methods are commonly employed to study such systems. In this paper we investigate the numerical calculation of quantum transport of electrons in spherical centered defect InGaAs/AlGaAs quantum dot (SCDQD). The simulation is based on the imaginary time...

In this paper the effects of transmittance, dispersion angle and diffusion length on the quantum efficiency of solar cells (QESC) have been simulated and investigated. Optical path technic is used for simulation. The results show that base thickness, diffusion length, dispersion angle, number of optical confinement path and transmission angles have an extremely effects on the QESC. Simulation r...

In 1982, Richard Feynman proposed that a quantum system would be more efficiently simulated by a computer based on the principles of quantum mechanics rather than by one based on classical mechanics [1]. Recently, it has been pointed out that it should be possible to efficiently approximate any desired Hamiltonian within the standard model of a quantum computer by a sparsely coupled array of tw...

With the increasing size of quantum processors, submodules that constitute processor hardware will become too large to accurately simulate on a classical computer. Therefore, one would soon have fabricate and test each new design primitive parameter choice in time-consuming coordination between design, fabrication, experimental validation. Here we show how can performance next-generation hardwa...

Quantum-computing ideas are applied to the practical and ubiquitous problem of fluid dynamics simulation. Hence, this paper addresses two separate areas of physics: quantum mechanics and fluid dynamics (or specially, the computational simulation of fluid dynamics). The quantum algorithm is called a quantum lattice gas. An analytical treatment of the microscopic quantum lattice-gas system is car...
