Superpolynomial quantum enhancement in polaritonic neuromorphic computing

摘要

Recent proof-of-principle experiments have demonstrated the implementation of.neuromorphic computing using exciton-polaritons,making use of coherent classical states [D.Ballarini et al.,Nano Lett.20,3506 (2020)].At the same time,it is expected that nonlinear exciton polaritons can reach a quantum regime forming nonclassical states.Here we consider theoretically the quantum nature of exciton-polaritons,and we predict a superpolynomial quantum enhancement in image recognition tasks.This is achieved within experimentally accessible parameters.
