Universal Quantum Computer Simulation of 50 Qubits on Europe`s First Exascale Supercomputer Harnessing Its Heterogeneous CPU-GPU Architecture
Hans De Raedt, Jiri Kraus, Andreas Herten +5
We have developed a new version of the high-performance Jülich universal quantum computer simulator (JUQCS-50) that leverages key features of the GH200 superchips as used in the J…
Quantum annealing inspired algorithms for the NISQ Era
Rijul Sachdeva, Vrinda Mehta, Manpreet Singh Jattana +2
We study algorithms inspired by quantum annealing that are suited for the NISQ era. First, we analyze approximate quantum annealing (AQA), which employs a discretized annealing ans…
Understanding the physics of D-Wave annealers: From Schrödinger to Lindblad to Markovian Dynamics
Vrinda Mehta, Hans De Raedt, Kristel Michielsen +1
Understanding the physical nature of the D-Wave annealers remains a subject of active investigation. In this study, we analyze the sampling behavior of these systems and explore wh…
Unraveling Reverse Annealing: A Study of D-Wave Quantum Annealers
Vrinda Mehta, Hans De Raedt, Kristel Michielsen +1
D-Wave quantum annealers offer reverse annealing as a feature allowing them to refine solutions to optimization problems. This paper investigates the influence of key parameters, s…
Performance of quantum annealing for 2-SAT problems with multiple satisfying assignments
Vrinda Mehta, Hans De Raedt, Kristel Michielsen +1
Using a specially constructed set of hard 2-SAT problems with four satisfying assignments, we study the scaling and sampling performance of numerical simulation of quantum annealin…
