New framework interprets quantum learning models via stochastic processes

A new research paper proposes a framework to interpret quantum learning models by representing them as stochastic processes. The work, led by Johannes Fankhauser, addresses the challenge that quantum dynamics typically violate the Chapman-Kolmogorov condition, making them difficult to decompose into meaningful intermediate transitions like classical Markovian processes. The proposed method models quantum channels as transition kernels on probability representations, introducing a trade-off between non-classicality (negativity) and dependence on past configurations (higher Markov order). This approach offers a way to interpret quantum dynamics as stochastic walks through a memory space, potentially approximating quantum deliberation processes and recovering classical machine learning models in certain regimes.
