Nature Communications today published research by a team comprising Scottish and South African researchers, demonstrating entanglement swapping and teleportation of orbital angular momentum 'patterns' of light. This is a crucial step towards realizing a quantum repeater for high-dimensional entangled states.
A new imaging technique makes it possible to precisely digitize clear objects and their surroundings, an achievement that has eluded current state-of-the-art 3-D rendering methods.
Where do cosmic rays come from? Solving a 50-year-old mystery, a collaboration of researchers has discovered it's much farther than the Milky Way.
Researchers from the Singapore University of Technology and Design and Shanghai Institute of Microsystems and Information Technology have strain-engineered a data storage material to store data by exploiting a process of avalanche atomic switching. Memory cells using this material substantially outperform state-of-the-art phase change memory devices.
The cyber team led by Dr. Mordechai Guri, head of research and development for BGU's Cyber Security Research Center (CSRC), shows how IR can be used to create a covert communication channel between malware installed on an internal computer network and an attacker located hundreds of yards outside or even miles away with direct line of sight. The attacker can use this channel to send commands and receive response messages.
Canadian and US researchers have taken an important step towards enabling quantum networks to be cost-effective and truly secure from attack. The experiments, by the team from the University of Calgary, the California Institute of Technology and the National Institute of Standards and Technology, Colorado, prove the viability of a measurement-device-independent quantum key distribution (QKD) system, based on readily available hardware.
Scarce metals are found in a wide range of everyday objects around us. They are complicated to extract, difficult to recycle and so rare that several of them have become "conflict minerals" which can promote conflicts and oppression. A survey at Chalmers University of Technology now shows that there are potential technology-based solutions that can replace many of the metals with carbon nanomaterials, such as graphene.
Researchers have developed a system that can simultaneously deliver watts of power and transmit data at rates high enough to stream video over the same wireless connection. By integrating power and high-speed data, a true single 'wireless' connection can be achieved.
The research study will help engineers to develop more different measures of the nature diagnosability based on application environment, network topology, network reliability, and statistics related to fault patterns.
IBS researchers produced the first 2-D field-effect transistor (FET) made of a single material.
