Memory closes in on single photons
(Phys.org) —In a world-first, an optical memory – a key component for quantum computers – has been created within a hollow-core optical fibre and shown to operate at the level of a single particle of ...
Nanostructured capsules could bring about paints and electronic displays that never fade
(Phys.org) —Among the taxidermal specimens in Harvard's Museum of Comparative Zoology, past centuries-old fur coats, arises a flicker of brilliant blue. This is the spangled cotinga. Surprisingly, the cotinga ...
Bending the light with a tiny chip
(Phys.org) —Imagine that you are in a meeting with coworkers or at a gathering of friends. You pull out your cell phone to show a presentation or a video on YouTube. But you don't use the tiny screen; your ...
Squeezing light into metals: Team controls conductivity with inkjet printer
Using an inexpensive inkjet printer, University of Utah electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls electrical conductivity ...
