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.

Distributed Tensor Principal Component Analysis with Data Heterogeneity

2024 · arXiv (Cornell University)

As tensors become widespread in modern data analysis, Tucker low-rank Principal Component Analysis (PCA) has become essential for dimensionality reduction and structural discovery in tensor datasets. Motivated by the common scenario where large-scale tensors are …
