Unidimensional continuous-variable quantum key distribution with imperfect detector
2019
We report a method to improve the performance of unidimensional continuous-variable quantum key distribution with imperfect detector by adding a parameter-adjustable optical amplifier, where the optimal performance can approach the scenario with a perfect detector.

Realizing downstream access network using continuous-variable quantum key distribution
2021 · arXiv (Cornell University)
Quantum key distribution (QKD) which enables the secure distribution of symmetric keys between two legitimate parties is of great importance in future network security. Access network that connects multiple end-users with one network backbone can …

Multi-Stage Network Embedding for Exploring Heterogeneous Edges
2021 · arXiv (Cornell University)
The relationships between objects in a network are typically diverse and complex, leading to the heterogeneous edges with different semantic information. In this paper, we focus on exploring the heterogeneous edges for network representation learning. …

<scp>HyGEN</scp> : Regularizing Negative Hyperedge Generation for Accurate Hyperedge Prediction
2025
Hyperedge prediction is a fundamental task to predict future high-order relations based on the observed network structure. Existing hyperedge prediction methods, however, suffer from the data sparsity problem. To alleviate this problem, negative sampling methods …
