Physorg January 11, 2018 A method of securely communicating between multiple quantum devices developed by researchers in the UK does not rely on assumptions, but instead it uses the quantum laws of physics to ensure security, which would need to be broken to hack the encryption. They report on a way of communicating securely between three or more quantum devices, irrespective of who built them. The method works by using the network’s structure to limit what an eavesdropper can learn. They used machine learning and causal inference to develop the test for the un-hackable communications system. This approach distributes secret […]

Engineers reinvent the inductor after two centuries
Nanotechweb January 15, 2018 An international team of researchers (USA – UC Santa Barbara, Japan, China) has made high-performance inductors from intercalated graphene that work in the 10-50 GHz range due to the mechanism of kinetic inductance rather than magnetic inductance. The new inductors, which have both small form-factors and high inductance values, of around 1-2 nanoHenry are a third smaller in terms of surface area than conventional devices but with the same performance. They might thus be used in ultra-compact wireless communication systems for applications in the IoT, sensing and energy storage/transfer. It also highlights a practical application for […]
FAU to develop novel real-time undersea wireless communications and surveillance technology
Eurekalert January 11, 2018 The current state-of-the-art approaches for undersea localization and tracking are expensive and power-intensive. Under an NSF grant, researchers at Florida Atlantic University will develop novel optimal algorithms for oceanic-scale 3D acoustic underwater localization and tracking, software and hardware technology to create and maintain a programmable software-defined undersea acoustic testbed comprising of four nodes. The new technology is expected to resolve interoperability issues in heterogeneous network deployments that include real-time interaction between undersea, water-surface, aerial, and satellite communication nodes… read more.
