Researchers of the Eindhoven University of Technology (TU/e) have developed a 'hybrid technology' which shows the advantages of both light and magnetic hard drives. Ultra-short (femtosecond) light pulses allows data to be directly written in a magnetic memory in a fast and highly energy-efficient way. This research, published in Nature Communications, promises to revolutionize the process of data storage in future photonic integrated circuits.
Researchers from the Singapore University of Technology and Design (SUTD) have invented a new type of anti-counterfeiting device that can be useful for counterfeit deterrence of important documents such as identity cards, passports and banknotes.
After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices.
NIMS succeeded in fabricating topological LC circuits arranged in a honeycomb pattern where electromagnetic (EM) waves can propagate without backscattering even when pathways turn sharply. These circuits may be suitable for use as high-frequency electromagnetic waveguides, which would allow miniaturization and high integration in various electronics devices, such as mobile phones.
Meteor burst communication is based on using meteors as cryptography assistants. Meteor trails reflect radio waves, which makes them suitable for radio transmissions at distances of up to 2,000 kilometers. Unpredictable nature of meteors makes pose a significant hindrance for signal interception.
Researchers in Italy have demonstrated the feasibility of quantum communications between high-orbiting global navigation satellites and a ground station, with an exchange at the single photon level over a distance of 20,000km. The milestone experiment proves the feasibility of secure quantum communications on a global scale, using the Global Navigation Satellite System (GNSS). It is reported in full today in the journal Quantum Science and Technology.
Researchers at the National Institute of Information and Communications Technology (NICT) and Tokyo University of Agriculture and Technology (TUAT) demonstrate a vertical Ga2O3 metal-oxide-semiconductor field-effect transistor (MOSFET) that adopts an all-ion-implanted process for both n-type and p-type doping, paving the way for new generations of low-cost and highly-manufacturable Ga2O3 power electronic devices.
Researchers at the National Institute of Standards and Technology (NIST) have developed a method for evaluating and selecting optimal antenna designs for future fifth-generation (5G) cellphones, other wireless devices and base stations.
Using a compact optical platform that exploits the quantum characteristics of light, Professor Roberto Morandotti and his team are one step closer to realizing the first powerful photonic quantum computer. In Nature Physics, the INRS researchers revealed to have generated a particular class of quantum states - d-level cluster states, robust and powerful than any other such states demonstrated thus far -, as well as to have used them to implement novel quantum operations.
New technology is designed to allow cellular communication nodes in 5G systems to partition bandwidth more efficiently in order to improve end-to-end data transmission rates. In simulations, the tech is capable of meeting the international goal of 10 gigabits per second in peak performance areas.
