- Abstract: Despite their theoretical importance, dynamic Bayesian networks associated
with quantum processes are currently not accessible experimentally. We here
describe a general scheme to determine the multi-time path probability of a
Bayesian network based on local measurements on independent copies of a
composite quantum system combined with postselection. We further show that this
protocol corresponds to a non-projective measurement. It thus allows the
investigation of the multi-time properties of a given local observable while
fully preserving all its quantum features.

We introduce an innovative multimodal learning approach, recognizing that the formalism of data in this task embodies two distinct modalities.

It is crucial to characterize the topology of networks in a way that reveals the nodes between which entanglement can be reliably distributed.
Our scheme allows for distinguishing, in a scalable manner, different networks consisting of bipartite and multipartite entanglement sources.
We experimentally demonstrate our approach by certifying the topology of different six-qubit networks generated with polarized photons.

We show how to predict and experimentally observe the emergence of random state ensembles naturally under time-independent Hamiltonian dynamics.
The observed random ensembles emerge from projective measurements and are intimately linked to universal correlations built up between subsystems of a larger quantum system.
Our work has implications for understanding randomness in quantum dynamics, and enables applications of this concept in a wider context.

The question of which correlations a given quantum network can give rise to, remains almost uncharted.
We show that constraints on the observable covariances, previously derived for the classical case, also hold for quantum networks.
