Research: Quantum Computing: Find journal articles and conference papers

M. Bönitz, Karsten Balzer

This is the fourth volume1 of articles on the theory of Nonequilibrium Green's functions (NEGF) and their modern application in various fields such as plasma physics, semiconductor physics, molecular electronics and high energy physics. It contains 23 articles written by experts in many-body theory and quantum transport who summarize recent progress in their respective area of research. The articles are based on talks given at the interdisciplinary conference Progress in Nonequilibrium Green's functions IV which was held 17–21 August 2009 at the University of Glasgow, Scotland. This conference continues the tradition of the previous meetings which started in 1999 and which aimed at an informal exchange across field boundaries. The previous meetings and the earlier proceedings proved to be very stimulating not only for young researchers but also for experienced scientists, and we are convinced that this fourth volume will be as successful as the previous ones. As before, this volume includes only extended review-type papers which are written in a way that they are understandable to a broad interdisciplinary audience. All papers published in this volume of Journal of Physics: Conference Series have been peer reviewed through processes administrated by the Editors assuring highest scientific standards. In the review process some papers were substantially revised and improved and some were rejected. This conference would not have been possible without the remarkable work of the local organizing team around John Barker and Scott Roy and the generous financial support from the University of Glasgow and the Deutsche Forschungsgemeinschaft via SFB-Transregio 24. Michael Bonitz and Karsten Balzer Kiel, February 2010 1 The first two volumes are Progress in Nonequilibrium Green's functions, M Bonitz (ed) and Progress in Nonequilibrium Green's functions II, M Bonitz and D Semkat (eds), which were published by World Scientific (Singapore), in 2000 and 2003, respectively (ISBN 981-02-4218-2 and ISBN 981-238-271-2). The third volume Progress in Nonequilibrium Green's functions III M Bonitz and A Filinov (eds) was published in Journal of Physics: Conference Series, volume 35 (2006).

Quantum Machine Learning (QML) has become one of the leading interdisciplinary applications in terms of computational sciences.It leverages quantum-computing principles for machine learning tasks, providing new computational concepts to address complex, high-dimensional problems.In this review article, we offer a comprehensive discussion of the theoretical foundation, algorithmic models, hardware limitations, and experimental realizations of QML.In other words, there is a very big difference between the speed improvements which quantum computing promises in the theory world and what we can actually achieve when running the algorithms in real world.The review consolidates the results from classical papers, reviews the hybrid architectures, and evaluates the challenges in reproducibility in the field.A Paper for a Scholarly Journal.The paper is scholarly and will be of use to scholars, researchers, teachers, and practitioners who attend national conferences.[8], [2]

This is the third volume (the first two volumes are Progress in Nonequilibrium Green's Functions , M. Bonitz (ed.) and Progress in Nonequilibrium Green's Functions II , M. Bonitz and D. Semkat (eds.), which were published by World Scientific (Singapore), in 2000 and 2003, respectively, (ISBN 981-02-4218-2 and ISBN 981-238-271-2).) of articles on the theory of Nonequilibrium Green's functions (NGF) and their modern applications in various fields. The refereed papers in this volume are based on talks and posters presented at the interdisciplinary conference Progress in Nonequilibrium Green's Functions III which was held in August 2005 at Kiel University, Germany. The conference was attended by about 70 scientists working in a variety of fields of theoretical physics, including plasma physics, solid state theory, semiconductor optics and transport, nanostructures, nuclear matter and high energy physics. Compared to the previous conferences, new topics were covered, such as transport theory for molecular systems, combinations of NGF with (time-dependent) density functional theory or dynamical mean field theory. This reflects modern developments in many-body theory. As with the two previous volumes, this one, hopefully, will be a valuable and stimulating reference for students and researchers from various fields. In contrast to the previous volumes, this one appears as a volume of Journal of Physics: Conference Series . This option was chosen as Journal of Physics: Conference Series offers free access to the online version which also contains color figures. This, hopefully, will increase the distribution of the articles to the scientific community. This conference would not have been possible without the generous financial support from the Deutsche Forschungsgemeinschaft (DFG) and without help from many people. We are particularly grateful to Andrea Fromm, Fanny Geisler and Doris Schulz from the local organizating committee in Kiel and Wolf Dietrich Kraeft (Rostock) for assistence in the final editing of the papers.
