World's Smallest Optical Switch Uses a Single Atom (gizmag.com)

Zothecula writes: The rapid and on-going development of micro-miniature optical electronic devices is helping to usher in a new era of photonic computers and light-based memories that promise super-fast processor speeds and ultra-secure communications. However, as these components are shrunk ever further, fundamental limits to their dimensions are dictated by the wavelength of light itself. Now researchers at ETH Zurich claim to have overcome this limitation by creating both the world's smallest optical switch using a single atom, and accompanying circuitry that appears to break the rules by being smaller than the wavelength of the light that passes through it.

Although I personally don't mind Slashdot straying slightly into more 'stuff that matters' than 'news for nerds', I would not at all miss all the clickbait articles, the rile-em-up-articles, the terrible teaser non-summaries and all the other disgraces to this community we have been experiencing for months and months now.

So yes, seconded. Crossing my fingers and hoping Slashdot is indeed back to greatness!
