RIKEN Scientists Create Precision Carbon Nanotubes for Single-Photon Quantum Technologies Carbon Nanotubes Emerge as Key Building Blocks for Quantum Communication RIKEN researchers have developed a method to precisely create carbon nanotubes that emit single photon from a specific point along their length. These tiny carbon structures could become a cornerstone of future light-based quantum technologies . Light already carries vast amounts of data across the globe through optical fibers . Harnessing it quantum properties , however, could deliver major advantages, including ultra-secure communication in which any attempted interception is immediately detectable. Breakthrough in quantum physics, photonics and advanced materials are regularly covered by FSNews365 , which tracks emerging technologies shaping the future of science. Such quantum communication systems depend on light sources that release photons one at a time . While several platforms can achieve this, carbon nanotubes ...

Newly Discovered Molecule Promises Smaller, Faster Computing Devices The Evolution of Computing Devices Today, we all carry, a highly capable computer in our hand — a mobile phone. Computers weren't always this compact. From the 1980s onwards they've shrunk in size and weight while vastly increasing their data storage and processing power. Still, the silicon at their core has physical limits to how small it can go. The Challenges of Silicon in Modern Computing "Over the past fifty years, transistor counts on a single chip have doubled biennially," observed Dr. Kun Wang, Assistant Professor of Physics at the University of Miami. "Yet we are now approaching silicon's physical limits, and miniaturizing components using the same materials we've relied on for half a century is becoming ever more challenging." Dr. Wang's Innovative Approach to Molecular Electronics It is a challenge that Dr. Wang and numerous colleagues in the field of molecular electr...
