Scalable Authentication and Optimal Flooding in a Quantum Network

Naomi R. Solomons et al.

Summary: The global interest in quantum networks is driven by the security provided by the laws of physics. Deploying quantum networks faces challenges in scaling the physical hardware and optimizing the network layers. This article discusses the usefulness of authentication-transfer and flooding protocols through experimental demonstrations on an eight-user quantum network test bed.

Quantum internet under random breakdowns and intentional attacks

Bingzhi Zhang et al.

Summary: As quantum networks scale up, errors become inevitable, similar to what happens with the internet. Waxman networks and scale-free QNs both exhibit linear decrease in quantum capacity under random breakdowns, but show sharp exponential decay with increasing attack fraction.

Quantum communication capacity transition of complex quantum networks

Quntao Zhuang et al.

Summary: The research suggests that in a quantum network, there is a threshold transition in capacity as the density of network nodes increases in highly connected networks, while less connected networks exhibit saturation in end-to-end capacity.

Satellite quantum communications: Fundamental bounds and practical security

Stefano Pirandola

Summary: Satellite quantum communications offer a promising approach to distributing completely secure keys over long distances, with this study focusing on the ultimate limits and achievable rates for key generation and entanglement distribution. The research covers a wide range of practical scenarios and effects, showing the feasibility of continuous variable quantum key distribution protocols for all configurations. Results indicate that satellite quantum communications may outperform ground-based quantum repeaters in certain scenarios.

Limits and security of free-space quantum communications

Stefano Pirandola

Summary: The study of free-space quantum communications requires tools from quantum information theory, optics, and turbulence theory. The paper provides analytical tools for assessing the composable finite-size security of coherent-state protocols in general conditions. The research shows the ultimate rates for key and entanglement distribution through a free-space link and the suitability of free-space channels for high-rate quantum key distribution.
