摘要： This paper presents a mathematical formalism for generative artificial intelligence (GAI). Our starting point is an observation that a “histories" approach to physical systems agrees with the compositional nature of deep neural networks. Mathematically, we define a GAI system as a family of sequential joint probabilities associated with input texts and temporal sequences of tokens (as physical event histories as in \cite{Gudder1998,Isham1994}). From a physical perspective on modern chips, we then construct physical models realizing GAI systems as open quantum systems. Finally, as illustration, we construct physical models in the Fock space over the Hilbert space of tokens realizing large language models based on a transformer architecture as open quantum systems.
