Projektbeschreibung
Ein näherer Blick auf die Rechenkapazitäten baldiger Quantengeräte
Welches Potenzial hat das Quantenrechnen? Haben Quantengeräte selbst bei einem Rauschen oder bei Einschränkungen in puncto Größe oder geometrischer Anordnung von Qubits einen Nutzen? Das ERC-finanzierte Projekt EQUIPTNT wird entsprechende Antworten liefern. Es charakterisiert die Rechenkapazitäten baldiger Quantengeräte, indem ihr Potenzial auf das Erreichen bahnbrechender Steigerungen der Informationsverarbeitungsleistung untersucht wird. Das Projekt forscht an neuen Quantenalgorithmen und ermöglicht Rechenfortschritte, während die Rauschtoleranz maximiert wird. Das Projekt bringt zudem Rauschniveau, Rechenleistung sowie die Menge und Art der verfügbaren Rechenressourcen in Einklang. Außerdem werden Werkzeuge zur Simulation der Mehrkörper-Quantendynamik von Informationsverarbeitungsanordnungen entwickelt.
Ziel
Progress in the fabrication, control and readout of systems consisting of a small number of qubits has catapulted quantum computation from a primarily theoretical pursuit into the lab. With the growing availability of small and relatively noise-free devices and the imminent arrival of larger next-generation equipment, new theoretical questions are being asked about the potential of quantum computation. In particular, one may ask if quantum computing devices may yield computational benefits even in the presence of noise or constraints on their size or geometrical layout of qubits.
The project EQUIPTNT will characterize the computational capabilities of near-term quantum devices by studying their potential to yield disruptive boosts in information-processing power. It will investigate and design new quantum algorithms adapted to limited hardware: the aim here is to provide computational advances while maximizing noise-tolerance without placing excessive demands on experimental capabilities. It will establish trade-off relations between noise levels, computational power, and the amount and nature of available computational resources. EQUIPTNT will also develop tools for simulating the quantum many-body dynamics of information-processing setups by classical algorithms, in order to pinpoint the origin of quantum advantage, and provide means for certifying the functionality of quantum hardware.
EQUIPTNT will establish new theoretical and algorithmic methods to address the question of ''best use'' for a given finite set of resources. Its interdisciplinary approach will yield novel principles for the design, simulation and validation quantum information processing protocols. Corresponding results will have direct application to near-term quantum devices, providing insights into the architecture and use of schemes tailored towards specific experimental platforms.
