Description du projet
Plate-forme photonique intégrée pionière pour les schémas de calcul
Les paradigmes bio-inspirés et quantiques sont deux approches émergentes de l’informatique qui visent à surmonter les limites des méthodes informatiques traditionnelles. Le projet PROMETHEUS, financé par l’UE, comblera le fossé entre l’informatique bio-inspirée et l’informatique quantique en développant une plateforme commune qui intègre les points forts des deux paradigmes. Le projet se concentrera sur la création d’une plateforme photonique intégrée qui combine l’évolutivité de l’informatique quantique et l’efficacité de l’informatique neuromorphique. La plateforme fera appel à un réseau dense et reconfigurable de guides d’ondes en silicium, alimenté par des déphaseurs non volatiles en titanate de baryum et des lasers à pointes sur puce, ce qui garantira une faible consommation d’énergie et un réglage à grande vitesse lors de la reconfiguration du réseau. Le conditionnement électro-optique sophistiqué fera de la plateforme PROMETHEUS un moteur hybride autonome pour les applications exigeantes.
Objectif
Bio-inspired and quantum paradigms have risen as the two main competitors aiming to address the inefficiency of “conventional” computational schemes. Up to now these two paradigms utilize non-overlapping routes towards addressing this common objective; routes that are challenging in terms of scalability and integration readiness. PROMETHEUS’ proposition aims to shatter the boundaries between neuromorphic and quantum engineering and merge them to a common disruptive photonic integrated platform, able to merge each field’s merits. The platform will be based on a dense reconfigurable silicon waveguide mesh, powered by non-volatile BaTiO3 phase-shifters offering marginal power consumption and GHz tuning speed, during mesh reconfiguration. A key “upgrade” to this “synaptic” platform will be the co-integration of ultra-fast, multi-section lasers, acting as “neurons”. Sophisticated electro-optic packaging, will provide the basis to PROMETHES’ platform so as to evolve from the proof-of-concept limbo to a standalone neuromorphic/quantum hybrid integrated engine. This versatile chip will enable the realization of neuromorphic architectures such as large-scale spiking neural networks by exploiting signal multiplexing and GHz firing rate, photonic time-based convolutional networks, liquid state machines and on-chip training. PROMETHEUS will render feasible the exploration of disruptive concepts such as quantum reservoir computing. The platform will be utilized as an integrated quantum random generator and as a physical unclonble function, adding physical layer trustworthiness and novel security features. PROMETHEUS’ chips will be benchmarked, in terms of consumption, accuracy, speed and versatility, in a set of demanding applications that extend from ultra-fast image processing for flow cytometry and machine vision, signal equalization and authentication in high-speed optical links to quantum key generation and distribution.
