Abstract

This thesis examines the creation of entanglement in open quantum systems through the application of quantum channels. The primary objective is to understand the transition from a product state, initially uncorrelated, to an entangled state upon the application of quantum channels. The study emphasizes the immediate effects of quantum channels on entanglement production, employing mathematical modeling and computational simulations to explore various system configurations and quantum channel parameters. Key results include the identification of conditions under which quantum channels produce only classical correlations and the determination of necessary and sufficient conditions for entanglement generation by specific subclasses of completely positive, trace-preserving (CPTP) maps.
