Description du projet
Un examen approfondi des capacités de calcul des dispositifs quantiques à court terme
Quel est le potentiel du calcul quantique? Les dispositifs de calcul quantique apportent-ils des avantages en matière de calcul, même en présence de bruit ou de contraintes concernant leur taille ou la disposition géométrique des qubits? Le projet EQUIPTNT, financé par le CER, tentera de répondre à cette question. Il caractérisera les capacités de calcul des dispositifs quantiques à court terme en étudiant leur potentiel à produire des augmentations perturbatrices de la puissance de traitement de l’information. Il étudiera de nouveaux algorithmes quantiques et proposera des avancées en matière de calcul tout en maximisant la tolérance au bruit. Le projet établira également des relations de compromis entre les niveaux de bruit, la puissance de calcul et la quantité et la nature des ressources informatiques disponibles. Il développera également des outils de simulation de la dynamique quantique à plusieurs corps des configurations de traitement de l’information.
Objectif
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.
