 From what I understand, by passing a photon through certain materials 
you may alter its quantum waveform. This means you can store 
information, such as images, on it. What the guys in NYC have done is to 
store an image onto a single photon's waveform by passing it through a 
kind of quantum stencil, then slowed it down by passing it through 
caesium gas. Slowing the photon down means you can effectively hold it 
for a (very) short period of time and therefore, keep the information it 
contains. I think it's awesomely cool. Commercial optical quantum 
computers by the time we're sixty? We might just be lucky...
