FPGA-Based Implementation of Size-Adaptive Privacy Amplification in Quantum Key Distribution

2017 · IEEE photonics journal

In a quantum key distribution (QKD) system, privacy amplification (PA) is an essential procedure that can effectively eliminate the leaked information to an eavesdropper and distill a secret key. The processing speed of the PA …

Finite-size analysis of unidimensional continuous-variable quantum key distribution under realistic conditions

2017 · Optics Express

We analyze the unidimensional (UD) continuous-variable quantum key distribution protocol in a finite size scenario under realistic conditions. The dependence of the secret key rate on realistic parameters is analyzed numerically. A method of calculating …

Acoustic Word Embedding System for Code-Switching Query-by-example Spoken Term Detection

2020 · ArXiv.org

In this paper, we propose a deep convolutional neural network-based acoustic word embedding system on code-switching query by example spoken term detection. Different from previous configurations, we combine audio data in two languages for training …

Exploring Voice Conversion based Data Augmentation in Text-Dependent Speaker Verification

2020 · arXiv (Cornell University)

In this paper, we focus on improving the performance of the text-dependent speaker verification system in the scenario of limited training data. The speaker verification system deep learning based text-dependent generally needs a large scale …
