Now at #MCQS, Andrea Rocchetto, from @UCL @UniofOxford on «Machine learning in quantum information theory, a selection of results» #LTQI
@ucl @UniofOxford Andrea Rocchetto defines the PAC (porbabilistically aproximate correct) models, and defines the concept of PAC-learnable: a concept is PAC-learnable iff one can guess a good model for arbitrary input distributions

@ucl @UniofOxford Andrea Rocchetto: PAC learning on quantum states. The goal is to guess σ havig the same probability ditribution under a binary POVM than the training set ρ. Aaronson proved in 2007 that the problem is really different from tomography. #LTQI #MCQS
