Topic: Quantum Bayesian Inference



At first, this talk will give introduction to Bayesian Networks [1] and their use cases, with particular focus on how they can be used to model games [2]. We will describe their quantum generalization by introducing  entanglements between the variables they model [3]. We will describe  two versions of quantum Bayesian inference algorithms.

Next, we will present AcausalNets.jl library for modeling quantum Bayesian networks and performing inference on them written in Julia language.  Finally, we will present our reproduction of experiments with a quantum version of Monty Hall game [2] performed with our software.
