“World’s smallest ball game” tosses single atoms between light traps

Scientists in South Korea have created what they call “the world’s smallest ball game,” throwing individual atoms between two optical traps. The research could eventually make for more adaptable and dynamic quantum computers.Continue ReadingCategory: S… Continue reading “World’s smallest ball game” tosses single atoms between light traps

Interesting Optical Journey Results in Hybrid Viewfinder for Smartphones

Fair warning: if you ever thought there was nothing particularly interesting with optical viewfinders, prepare to have your misconception corrected by [volzo] with this deep-dive into camera-aiming aids that leads …read more Continue reading Interesting Optical Journey Results in Hybrid Viewfinder for Smartphones

Remote controlled worms can follow stop and go lights

Scientists in Japan have demonstrated a technique that essentially allows them to remotely control the movements of worms. By implanting light-sensitive proteins into the organisms, the team was able to make them move under green light and stop under U… Continue reading Remote controlled worms can follow stop and go lights

Speed record shattered for data transmission over standard optical fiber

Engineers have set a new speed record for data transmission through a standard diameter optical fiber. By beaming 55 “modes” of signals down a single-core optical fiber, the team was able to transmit at a data rate of 1.53 petabits per second (Pbit/s)…. Continue reading Speed record shattered for data transmission over standard optical fiber

“64-dimensional quantum space” drastically boosts quantum computing

Scientists have demonstrated a powerful technique that will allow quantum computers to store much more information in photons of light. The team managed to encode eight levels of data into photons and read it back easily, representing an exponential le… Continue reading “64-dimensional quantum space” drastically boosts quantum computing

Ultrathin metasurface produces web of quantum entangled photons

Scientists at Sandia National Laboratories and the Max Planck Institute have developed a way to produce a web of quantum entangled photons using a far more simple setup than usual. The key is a precisely patterned surface 100 times thinner than paper, … Continue reading Ultrathin metasurface produces web of quantum entangled photons

Nanopillared lenses let scientists trap individual atoms with light

“Optical tweezers” – systems that focus light to trap and manipulate individual atoms – could pave the way for powerful quantum devices, but they can be a little cumbersome. Researchers have now developed a simplified, smaller design for optical tweeze… Continue reading Nanopillared lenses let scientists trap individual atoms with light
