From: Quantum stochastic walks for portfolio optimization: theory and implementation on financial networks
Conceptual illustration of the quantum stochastic walk (QSW) as a dual-channel engine on a financial graph: a coherent channel (purple) explores correlated clusters through Hamiltonian evolution, while a stochastic channel (blue) implements Google-type jumps that enforce diversification and guarantee convergence to a unique stationary state.
