New dual band stabilisation technique cancels the problem of temperature fluctuations to allow long distance quantum communication. Quantum key distribution demonstrated on fibres of record 600km length. Significant advance towards building a global quantum internet.
The world is one step closer to ultimately secure conference calls, thanks to a collaboration between Quantum Communications Hub researchers and their German colleagues, enabling a quantum-secure conversation to take place between four parties simultaneously.
Scientists have created a cybersecurity technology called Shadow Figment that is designed to lure hackers into an artificial world, then stop them from doing damage by feeding them illusory tidbits of success. The aim is to sequester bad actors by captivating them with an attractive--but imaginary--world. The technology is aimed at protecting physical targets--infrastructure such as buildings, the electric grid, water and sewage systems, and pipelines.
This research investigated the information-theoretic complexity of fungal electrical activity and pave the way for additional investigation into sensorial fusion and fungi decision making
Scientists at Sandia National Laboratories have built the world's smallest and best acoustic amplifier. And they did it using a concept that was all but abandoned for almost 50 years.
* ICFO researchers report in Nature on having achieved, for the first time, entanglement of two multimode quantum memories located in different labs separated by 10 meters, and heralded by a photon at the telecommunication wavelength. * The study has been selected to grace the cover of Nature magazine.
Scientists at Tokyo Institute of Technology have developed a wirelessly powered relay network for 5G systems. The proposed battery-free communication addresses the challenges of flexible deployment of relay networks. This design is both economical and energy-efficient. Such advances in 5G communications will create tremendous opportunities for a wide range of sectors.
Current wireless networks such as Wi-Fi, LTE-Advanced, etc., work in the lower radio spectrum, below 6 GHz. Experts warn that soon this band will become congested due to mushrooming data traffic. It is calculated that by 2024, 17,722 million devices will be connected.
Researchers at Brigham Young University have built a new analog-to-digital converter (ADC) -- a tiny piece of technology present in almost every electronic piece of equipment that converts analog signals (like a radio wave) to a digital signal -- with record-breaking power efficiency. The ADC consumes only 21 milli-Watts of power at 10GHz for ultra-wideband wireless communications.
The Cybersecurity Laboratory of the National Institute of Information and Communications Technology (NICT) has enhanced its cyber attack integrated analysis platform "NIRVANA Kai" to support the Internet Protocol version 6 (IPv6), the successor to IPv4. NIRVANA Kai has succeeded in real-time visualization of packets flowing in the vast address space of IPv6 for the first time in the world. It is expected to be useful for security measures for more diverse and extensive networks.
