    Ein Quantensprung? - Neuste Entwicklungen im Quantencomputing

    Get PDF
    Bei der Berechnung großer Probleminstanzen stoßen klassische Rechner bereits heute an ihre Grenzen. Die wachsende Komplexität der Aufgabenstellungen erfordert daher die Erforschung neuer Rechnerarchitekturen. Es zeigen sich deutliche Hinweise, dass die Ausnutzung quantenmechanischer Prinzipien einen entscheidenden Vorteil gegenüber klassischen Systemen liefert: Quantenbits können sich zugleich im Zustand „0“ und „1“ befinden und somit beide Werte simultan manipuliert werden. Durch diese Quantenparallelität weisen Quantenalgorithmen eine geringere Laufzeit als ihre klassischen Gegenstücke auf. Von einer praktischen Nutzbarkeit sind aktuelle Realisierungen des universellen Quantencomputers jedoch weit entfernt. Von der Firma D-Wave Systems Inc. ist hingegen ein sogenannter adiabatischer Quanten-Annealer kommerziell verfügbar. Durch die Transformation von Quantensystemen können damit spezielle Optimierungsprobleme gelöst werden. Deren eingeschränkte Struktur erschwert jedoch die Übertragung von Anwendungsproblemen. Betrachtet wurden dazu zum einen ein vereinfachtes Modell einer Satellitenmissionsplanung und zum anderen ein Luftverkehrsmanagementproblem aus einem Kooperationsprojekt mit der NASA. Zu letzterem wurden bereits erfolgreich Berechnungen auf der Maschine durchgeführt. Obwohl die Überlegenheit des adiabatischen Quanten-Annealing noch nicht zweifelsfrei nachgewiesen werden konnte, zeigt dies die Lösbarkeit von Problemen der Luft- und Raumfahrt

    Research reports: 1991 NASA/ASEE Summer Faculty Fellowship Program

    The basic objectives of the programs, which are in the 28th year of operation nationally, are: (1) to further the professional knowledge of qualified engineering and science faculty members; (2) to stimulate an exchange of ideas between participants and NASA; (3) to enrich and refresh the research and teaching activities of the participants' institutions; and (4) to contribute to the research objectives of the NASA Centers. The faculty fellows spent 10 weeks at MSFC engaged in a research project compatible with their interests and background and worked in collaboration with a NASA/MSFC colleague. This is a compilation of their research reports for summer 1991

    The Second Conference on Lunar Bases and Space Activities of the 21st Century, volume 1

    Get PDF
    These papers comprise a peer-review selection of presentations by authors from NASA, LPI industry, and academia at the Second Conference (April 1988) on Lunar Bases and Space Activities of the 21st Century, sponsored by the NASA Office of Exploration and the Lunar Planetary Institute. These papers go into more technical depth than did those published from the first NASA-sponsored symposium on the topic, held in 1984. Session topics covered by this volume include (1) design and operation of transportation systems to, in orbit around, and on the Moon, (2) lunar base site selection, (3) design, architecture, construction, and operation of lunar bases and human habitats, and (4) lunar-based scientific research and experimentation in astronomy, exobiology, and lunar geology
