Abstract

In this tutorial, we review the fundamentals of quantum mechanics and introduce master equations for open quantum networks as a foundational model for distributed quantum control and quantum computing. We then demonstrate how classical consensus theory can be extended to the quantum regime, where quantum parallelism naturally emerges from the dynamical interactions described by a quantum Laplacian framework. Finally, we show that the blended dynamics theory developed for classical networks can be generalized to quantum networks, providing concrete explanations for observed quantum phenomena in spin networks and other quantum systems.
