Abstract
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.
