Storing Photons In a Solid State Device

Posted by timothy on from the next-year-in-vending-machines dept.

bondisthebest writes in with a report from IEEE Spectrum: "Physicists in Switzerland, led by Nicolas Gisin of the University of Geneva, reported last week in Nature that they have made a solid-state device capable of storing photons for as long as 1 microsecond. The invention will aid in the development of light-based quantum-cryptography networks, which are theoretically impervious to hacking but are currently limited in range to a few dozen kilometers, primarily because of a lack of a suitable way to store the quantum state of photons."

    Wow, they've figured out how to store photons for about as long as my three-year-old obeys a command to stop fidgeting.

    From TFA: What they did was "find a way to trap a photon in a collection of 10 million neodymium atoms embedded in an yttrium orthovanadate crystal". Now say that 10 times fast. :-)
