(author), Capellini, G. (author)A strained Ge quantum well, grown on a SiGe/Si virtual substrate and hosting two electrostatically defined hole spin qubits, is nondestructively investigated by synchrotron-based scanning X-ray diffraction microscopy to determine all its Bravais lattice parameters. This allows rendering the three-dimensional spatial dependence of the six strain...article 2023

Neumann, N.M.P. (author), de Heer, P.B.U.L. (author), Phillipson, F. (author)In this paper, we present implementations of an annealing-based and a gate-based quantum computing approach for finding the optimal policy to traverse a grid and compare them to a classical deep reinforcement learning approach.We extended these three approaches by allowing for stochastic actions instead of deterministic actions and by...article 2023

Dukalski, M. (author), Rovetta, D. (author), van der Linde, S.G. (author), Möller, M. (author), Neumann, N. (author), Phillipson, F. (author)Much of recent progress in geophysics can be attributed to the adaptation of heterogeneous high-performance computing architectures. It is projected that the next major leap in many areas of science, and hence hopefully in geophysics too, will be due to the emergence of quantum computers. Finding a right combination of hardware, algorithms, and...article 2023

van der Schoot, W.E. (author), Leermakers, D. (author), Wezeman, R.S. (author), Neumann, N.M.P. (author), Phillipson, F. (author)We report the Atos Q-score for D-Wave’s quantum devices, classical algorithms and hybrid quantum-classical solver. Computing the Q-score entails solving the Max-Cut problem for increasingly large graphs. This work presents the first computation of the Q-score on a quantum device and shows how these quantum devices compare to classical devices at...conference paper 2022

Phillipson, F. (author), Chiscop, I. (author)Matching electricity demand and supply by decentralised generators will be very important in the near future, where more and more electricity has to be produced sustainably. Optimisation problems that address this problem often have quadratic objective functions or constraints, due to the quadratic nature of energy loss. Where classical solvers...conference paper 2022

(author)Radar and sonar information processing is a promising application area of quantum computing in the near future. Many use cases in this area can are computational heavy and might benefit greatly from a quantum approach. In this paper, an overview of use cases in this application area is given and scored on quantum readiness, added value and...conference paper 2022

Neumann, N.M.P. (author), Wezeman, R.S. (author)Quantum computers can solve specific complex tasks for which no reasonable-time classical algorithm is known. Quantum computers do however also offer inherent security of data, as measurements destroy quantum states. Using shared entangled states, multiple parties can collaborate and securely compute quantum algorithms. In this paper we propose...conference paper 2022

Wezeman, R.S. (author), Chiscop, I. (author), Anitori, L. (author), van Rossum, W.L. (author)Compressive sensing is a signal processing technique used to acquire and reconstruct sparse signals using significantly fewer measurement samples. Compressive sensing requires finding the most sparse solution to an underdetermined linear system, which is an NP-hard problem and as a consequence in practise is only solved approximately. In our...conference paper 2022
