Editorial: Quantum computing applications in computational engineering
Quantum computing research is a very active and diverse area of research, including work on creating quantum processing hardware in addition to investigations of applications with the potential for significant speed-up over simulations on classical (non-quantum) computers. The focus of this Research Topic is on applications in computational science and engineering. For these applications, the development of effective quantum algorithms with a significant speed-up over classical algorithms running on classical computers, has shown limited overall progress and is still in its infancy. However, this area of research has seen significant growth and progress in recent years, as illustrated by the three articles in this Research Topic. The three articles in this Research Topic present advances in the development of quantum algorithms for applications in computational engineering, in particular computational fluid dynamics and structural mechanics. Two of the articles focus on original research in the area of computational fluid dynamics, while the third article provides a detailed review of existing work and prospects for quantum computing for partial differential equations in structural mechanics. Focusing on the concept of quantum annealing, the article by Ray et al. explores the feasibility of using quantum annealers for the simulation of fluid flows. In the literature, this approach has not been widely investigated. In their article, Ray et al. consider the wellstudied flow problem comprising the fully-developed pressure-driven flow between two infinite flat plates so that a linear, quasi-one-dimensional problem emerges. They then describe a framework to convert this type of problem in terms of an optimization problem suitable for use on quantum annealers. The D-Wave annealer (D-Wave, 2022) used in this work returns multiple states that sample the energy landscape of the problem and therefore the authors explore different solution selection strategies to approximate the solution of the problem. The obtained solutions are analyzed both qualitatively and quantitatively, showing, for example, the sensitivity to the precision used in the fixed-point representation of the velocity data. In recent years, a major research focus in quantum computer applications to fluid dynamics has been lattice-based modeling, in particular approaches based on the Lattice Boltzmann method, e.g., Todorova and Steijl (2020); Budinski (2021); Budinski (2022).
