Quantum machine learning with adaptive linear optics [PDF]

open access: yesQuantum, 2021
We study supervised learning algorithms in which a quantum device is used to perform a computational subroutine – either for prediction via probability estimation, or to compute a kernel via estimation of quantum states overlap. We design implementations
