Abstract

Simulations of standard 1D and 2D quantum walks have been performed within Quantum Computer Simulator (QCS system) environment and with the use of GPU supported by CUDA technology. In particular, simulations of quantum walks may be seen as an appropriate benchmarks for testing calculational power of the processors used. It was demonstrated by a series of tests that the use of CUDA based technology radically increases the computational power compared to the standard CPU based computations.
