Entangling photons of different colors

Some of the most advanced communication systems now under development rely on the properties of quantum science to store and transport information. However, researchers designing quantum communication systems that rely on ...

Looking past the hype about 'trackless trams'

The optically guided bus is the latest in a long line of initiatives to repackage the bus as premium rail-derived technology. The name "trackless trams", the vehicle design, and the modest deployment costs all have broad ...

How microscopic machines can fail in the blink of an eye

How long can tiny gears and other microscopic moving parts last before they wear out? What are the warning signs that these components are about to fail, which can happen in just a few tenths of a second? Striving to provide ...

Scientists revolutionize cybersecurity through quantum research

Scientists at the RDECOM Research Laboratory, the Army's corporate research laboratory (ARL) have found a novel way to safeguard quantum information during transmission, opening the door for more secure and reliable communication ...

HD video from the moon in near real time

A new optical modem, capable of sending high-definition quality video significantly faster than standard radio frequency systems, is being developed for NASA's Orion spacecraft. The hardware, offered by LGS Innovations, is ...

'Folded' optical devices manipulate light in a new way

The next generation of electronic devices, ranging from personal health monitors and augmented reality headsets to sensitive scientific instruments that would only be found in a laboratory, will likely incorporate components ...
