Abstract: A bstractWe introduce a new information-theoretic measure of multipartite correlations ΔP, by generalizing the entanglement of purification to multipartite states. We provide proofs of its various properties, focusing on several entropic inequalities, in generic quantum… read more here.

Abstract: We introduce entanglement purification protocols for d-level systems (qudits) with improved efficiency as compared to previous protocols. While we focus on protocols for bipartite systems, we also propose generalizations to multi-partite qudit systems. The schemes… read more here.

DOI: 10.3390/e25050705
Abstract: It has been found that logic-qubit entanglement has great potential for applications in quantum communication and quantum networks in recent years. However, along with the effects of noise and decoherence, the fidelity of the communication… read more here.
