Omnisolver: An extensible interface to Ising spin-glass and QUBO solvers: adding a distributed GPU brute-force plugin
Konrad Jałowiecki, Jakub Pawłowski, Bartłomiej Gardas +1
This software update extends Omnisolver with \texttt{omnisolver-bruteforce}, a first-class plugin for exact exhaustive search of QUBO and Ising instances on CUDA-enabled GPUs. The…
PyQBench: a Python library for benchmarking gate-based quantum computers
Konrad Jałowiecki, Paulina Lewandowska, Łukasz Pawela
We introduce PyQBench, an innovative open-source framework for benchmarking gate-based quantum computers. PyQBench can benchmark NISQ devices by verifying their capability of discr…
Extraction of ergotropy: free energy bound and application to open cycle engines
Tanmoy Biswas, Marcin Łobejko, Paweł Mazurek +2
The second law of thermodynamics uses change in free energy of macroscopic systems to set a bound on performed work. Ergotropy plays a similar role in microscopic scenarios, and is…
Quantum annealing in the NISQ era: railway conflict management
Krzysztof Domino, Mátyás Koniorczyk, Krzysztof Krawiec +3
We are in the Noisy Intermediate-Scale Quantum (NISQ) devices' era, in which quantum hardware has become available for application in real-world problems. However, demonstrating th…
Quantum computing approach to railway dispatching and conflict management optimization on single-track railway lines
Krzysztof Domino, Mátyás Koniorczyk, Krzysztof Krawiec +2
In this work, we consider a practical railway dispatching problem: delay and conflict management on a single-track railway line. We examine the issue of train dispatching consequen…
Parallel in time dynamics with quantum annealers
Konrad Jałowiecki, Andrzej Więckowski, Piotr Gawron +1
Recent years have witnessed an unprecedented increase in experiments and hybrid simulations involving quantum computers. In particular, quantum annealers. Although quantum supremac…
Brute-forcing spin-glass problems with CUDA
Konrad Jałowiecki, Marek M. Rams, Bartłomiej Gardas
We demonstrate how to compute the low energy spectrum for small (), but otherwise arbitrary, spin-glass instances using modern Graphics Processing Units or similar heterog…
Approximate optimization, sampling and spin-glass droplets discovery with tensor networks
Marek M. Rams, Masoud Mohseni, Daniel Eppens +2
We devise a deterministic algorithm to efficiently sample high-quality solutions of certain spin-glass systems that encode hard optimization problems. We employ tensor networks to…
