Quantum conference key agreement (QCKA) allows multiple users to establish a secure key
from a shared multi-partite entangled state. In a quantum network, this protocol can be …

We study the performance (rate and fidelity) of distributing multipartite entangled states in a
quantum network through the use of a central node. Specifically, we consider the scenario …

Quantum conference key agreement is an important cryptographic primitive for future
quantum network. Realizing this primitive requires high-brightness and robust multiphoton …

Currently most progress on quantum secret sharing suffers from rate-distance bound, and
thus the key rates are limited. In addition to the limited key rate, the technical difficulty and …

We consider the task of device-independent quantum state certification in a network where
some of the nodes may collude and act dishonestly. We introduce the paradigm of self …

Twin-field quantum key distribution (TFQKD) enables two distant parties to establish a
shared secret key, by interfering weak coherent pulses (WCPs) in an intermediate …

Quantum information processing architectures typically only allow for nearest-neighbor
entanglement creation. In many cases, this prevents the direct generation of GHZ states …

Quantum networks aim to enable quantum information tasks among multiple parties.
Quantum conference key agreement (QCKA) is a typical task in quantum networks, which …

Quantum conferencing enables multiple nodes within a quantum network to share a secure
conference key for private message broadcasting. The key rate, however, is limited by the …

Multipartite entanglement enables secure and anonymous key exchange between multiple
parties in a network. Greenberger-Horne-Zeilinger states have been introduced as resource …
