Storing an entire image on a single photon

It gets into that whole wave/particle quantum thing: a team led by associate professor John Howell at the University of Rochester passed a single photon through a stencil bearing the letters UR. But since a photon is both a particle and a wave, as a wave, it passed through the entire stencil and thus captured its “shadow.” Then Howell was able to slow the photon down and retrieve it–and the image–intact.

Even Howell admits that it “sounds kind of impossible.” Nevertheless, he did it.

“Now I want to see if we can delay something almost permanently, even at the single photon level,” says Howell. “If we can do that, we’re looking at storing incredible amounts of information in just a few photons.”
