Simulation of Quantum Walks using HPC

We describe program Hiperwalk, which is a new simulator of the main quantum walk models using high-performance computing (HPC). The simulator is able to generate the dynamics of discrete-time quantum walks and staggered quantum walks, and will be able simulate continuous-time quantum walks and Szegedy’s quantum walks. It has an user-friendly input and is able to use hybrid HPC architectures, which includes the main ones available nowadays. The simulator outputs the main statistics associated with the probability distribution of the quantum walk in data files and automatically generates plots. The simulator uses open-source non-proprietary codes and employs freeware languages: Python, Neblina, Gnuplot, and OpenCL.
