Abstract: We quantify the entanglement and its variations via generalized concurrence, Meyer–Wallach measure and its generalizations. Then we investigate the interactions between qubits on complete graphs, tree graphs, chain graphs and loop graphs with 3 to… read more here.

Abstract: Quantifying entanglement in quantum systems is an important yet challenging task due to its NPhard nature. In this work, we propose an efficient algorithm for evaluating distance-based entanglement measures. Our approach builds on Gilbert’s algorithm… read more here.
