This could make all of our current storage mediums of today look as advanced as knotted strings in a few years.
“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.”
Sounds a bit like a holographic process:
To produce the UR image, Howell simply shone a beam of light through a stencil with the U and R etched out. Anyone who has made shadow puppets knows how this works, but Howell turned down the light so much that a single photon was all that passed through the stencil. Quantum mechanics dictates some strange things at that scale, so that bit of light could be thought of as both a particle and a wave. As a wave, it passed through all parts of the stencil at once, carrying the "shadow" of the UR with it.
My biggest question is how will you back up all of your data, assuming that this is used for anything but short term buffers.
