Quantum communication without entanglement could perform faster than previously thought possible
New way to store light could prove useful for optical communication
Researchers develop new type of fluorescent camera for blood diagnostics, brain mapping
(Phys.org) —Fluorescence imaging is the most widely used method for analyzing the molecular composition of biological specimens. Target molecules, when they are present, can be "tagged" with a fluorescent ...
New approach enhances quantum-based secure communication
University of Calgary scientists have overcome an 'Achilles' heel' of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets.
Wireless devices go battery-free with new communication technique
(Phys.org) —We might be one step closer to an Internet-of-things reality. University of Washington engineers have created a new wireless communication system that allows devices to interact with each other ...
Laser-like photons signal major step towards quantum 'Internet'
The realisation of quantum networks is one of the major challenges of modern physics. Now, new research shows how high-quality photons can be generated from 'solid-state' chips, bringing us closer to the ...
New algorithm for message dissemination in decentralized networks faster than its predecessors and guarantees delivery
Ad hoc networks—communication networks set up on the fly by mobile sensors—pose problems that ordinary office networks don't. Ad hoc networks are usually decentralized, meaning that no one node knows ...
Quantum entanglement with notification
(Phys.org) -- German scientists have demonstrated a method of heralding entanglement between distant stationary quantum systems without destroying this particular state. The experimental set-up paves the way ...
Daedalus catches cyber-attacks realtime
Hackers plot DIY Sputniks for Internet freedom
Beam me up ... Quantum teleporter breakthrough
(PhysOrg.com) -- Researchers have achieved a breakthrough in quantum communications and computing using a teleporter and a paradoxical cat.
Interpersonal trust erodes over time in the online world, experts say
When people interact in an Internet community, they experience higher levels of trust initially. But as time passes and more information comes to light about other users, they are more wary, according to ...
Research on social networks in late pre-Hispanic Southwest could have implications for crisis management today
The more you know your neighbors, the better off you may be when disaster strikes, a new study from the University of Arizona suggests.
Chattanooga touts transformation into Gig City
A city once infamous for the smoke-belching foundries that blanketed its buildings and streets with a heavy layer of soot is turning to lightning-fast Internet speeds to try to transform itself into a vibrant ...
