This is nothing short of astounding

Researchers at the University of Rochester have made an optics breakthrough that allows them to encode an entire image's worth of data into a photon, slow the image down for storage, and then retrieve the image intact.

Did you get that? An entire image, encoded onto ONE PHOTON? And then stored, and then recalled?

This is mindblowing to me. If you're at all interested in this, read the whole story here.
