Simulating Quantum Devices

Talk will be given by Łukasz Pawela from Quantum Programming Laboratory, ITAI PAS.

Abstract
The rapidly developing field of quantum information brings us ever closer to developing practical quantum computers. Currently, we are living in an era marked by the so-called Noisy Intermediate-Scale Quantum (NISQ) devices. It comes as no surprise that these machines have attracted attention from both the scientific and business communities. This attention results in a myriad of proposed potential applications for NISQ devices. One of the potential obstacles in developing quantum software, which this work aims to remedy, is the cost of testing on actual NISQ devices. The main way to cut quantum infrastructure access costs is to utilize frameworks that simulate their behavior. Nonetheless, if we try this approach, we quickly run into another problem: there are multiple frameworks available, each of which can be based on different numerical algorithms. Here, we are concerned with one particular NISQ architecture – the D-Wave annealer. The behavior of this machine can be simulated using a tensor network approach, dynamical system approach, neural networks and, for sufficiently small problem sizes, through a brute-force approach.
