Spreading of Information on a Network: A Quantum View

Entropy (Basel). 2023 Oct 11;25(10):1438. doi: 10.3390/e25101438.

Abstract

This paper concerns the modeling of the spread of information through a complex, multi-layered network, where the information is transferred from an initial transmitter to a final receiver. The mathematical model is deduced within the framework of operatorial methods, according to the formal mathematical apparatus typical of quantum mechanics. Two different approaches are considered: one based on the (H,ρ)-induced dynamics and one on the Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) equation. For each method, numerical results are presented.

Keywords: (H,ρ)-induced dynamics; GKSL equations; Heisenberg dynamics; operatorial models; spreading of information.
