Storing a Picture on One Photon

Before and After Image on a Photon


Scientists at the University of Rochester have figured out a way to store entire images on a single photon. From the article:
"It sort of sounds impossible, but instead of storing just ones and zeros, we're storing an entire image," says John Howell, associate professor of physics and leader of the team that created the device, which is revealed in today's online issue of the journal Physical Review Letters. "It's analogous to the difference between snapping a picture with a single pixel and doing it with a camera—this is like a 6-megapixel camera."

Yes, they've worked out how to store a hundred low-res images like that one in a block the size of a hard drive.

there's a way to go yet before you'll need to buy an SATA to optical converter.

this is not storage the MASK 'holds' the info. the single photon part is simply to illustrate that they didn't need high light levels just to get the light to EXIT.
