Quantum cryptography with multipartite entanglement
Speaker: Gláucia Murta | Heinrich Heine University Düsseldorf
Abstract
Quantum cryptography explores the use of quantum information to perform cryptographic tasks. Quantum systems bring advantages, such as the possibility of new functionalities or better security guarantees, but also challenges, resulting from the capabilities of quantum adversaries.
In this talk, we focus on cryptographic tasks that involve several parties and we investigate protocols based on multipartite quantum correlations. In particular, we consider the performance of conference key agreement - which aims to establish a common secret key shared by many participants - and variants of this task where, additionally, anonymity is imposed - namely, the identities of the participants are hidden from the remaining parties in a network. We compare the performance of protocols based on multipartite entanglement with protocols that implement the respective tasks using only bipartite entanglement.
