Quantum Key Distribution (QKD) offers unconditional security in principle. Many QKD protocols have been proposed and demonstrated to ensure secure communication between two authenticated users. Continuous variable (CV) many advantages over discrete (DV) since it is cost-effective, compatible with current classical technologies, efficient even daylight, gives a higher key rate. Keeping this view...

Continuous-variable measurement-device-independent quantum key distribution (CV-MDI-QKD) allows remote parties to share information-theoretical secure keys while defending all the side-channel attacks on measurement devices. However, transmission distance and secret rate are quite limited due high untrusted equivalent excess noise in Gaussian modulation. More particularly, extremely high-effici...

This paper studies an information-theoretic one-shot variable-length secret key agreement problem with public discussion. Let X and Y be jointly distributed random variables, each taking values in some measurable space. Alice Bob observe respectively, can communicate interactively through a noiseless channel, want to agree on length that is approximately uniformly over all bit sequences the agr...

Deep neural networks (DNNs) have been employed in continuous-variable quantum key distribution (CV-QKD) systems as attacking detection portions of defense countermeasures. However, the vulnerability DNNs leaves security loopholes for hacking attacks, example, adversarial attacks. In this paper, we propose to implement one-pixel attack CV-QKD and accomplish misclassification on a minimum perturb...

The number of potentially-related data resources available for querying — databases, data warehouses, virtual integrated schemas — continues to grow rapidly. Perhaps no area has seen this problem as acutely as the life sciences, where hundreds of large, complex, interlinked data resources are available on fields like proteomics, genomics, disease studies, and pharmacology. The schemas of indivi...
