Extensive research on stages 2 and 3 of this process has been carried out over the last 30 years. While there is still room for improvement, our understanding of the statistical processes involved in a statistical disclosure are now quite sophisticated. This is not true of stage 1, where our understanding is comparatively crude. This was the problem that drove the development of the metadata re...

Existing experimental implementations of continuous-variable quantum key distribution require shot-noise limited operation, achieved with shot-noise limited lasers. However, loosening this requirement on the laser source would allow for cheaper, potentially integrated systems. Here, we implement a theoretically proposed prepare-and-measure continuous-variable protocol and experimentally demonst...

This is an interesting case series on a very common genetic condition which are often diagnosed late as clinical signs are inconspicuous. We would like to highlight the principal clinical examination finding which led to diagnosis.

Today, we face a growing interest in distributed businessto-business applications using the Internet as communication media. However, the involved security threats are often neglected in the design of such systems. In this paper, we present our security architecture for an Internet based virtual trading community. Our solution has been designed for an heterogeneous, distributed workflow managem...

Abstract Continuous-variable quantum key distribution (CVQKD) has potential advantages of high secret rate, which is very suitable for high-speed metropolitan network application. However, the rates reported CVQKD systems are only a few Mbps over typical transmission distance so far. Here, we address fundamental experimental problems and demonstrate single-carrier four-state with sub-Gbps rate ...
