TL;DR: We propose a novel hardware platform for quantum state tomography and quantum state generation.

Abstract: We propose photonic integrated circuits augmented with a chi(3) nonlinearity -- e.g., a semiconductor exciton-polariton nonlinearity -- to accomplish two fundamental tasks in quantum processing: quantum state tomography and quantum state generation. We demonstrate in simulations that the design of the circuit can be optimized to great effect and showcase the efficacy of the optimized nonlinear circuits for the quantum machine learning tasks of i) fully identifying a family of emblematic quantum states and ii) stabilizing an accurate train of single photons.
