Abstract

Multi-partite entanglement is a key resource for many applications in quantum information technologies. Based on two material platforms, we consider methods for entanglement generation. In quantum-dot molecules [1], electric-field switching is used, and we characterize the separation between adiabatic and diabatic dynamics in the realization of entangled target states. Our numerical simulations are based on the Bloch-Redfield formalism and are a key step towards the realization of fully quantum-mechanical protocol simulation. As a second platform, we demonstrate the realization of multi-partite entangled states in coupled-cavity arrays and discuss their role in novel quantum machine learning concepts like quantum reservoir computing, to which we provide some insight.
