Physicists at the University of Rochester have made a breakthrough in data storage technology, namely, they've been able to store an entire image within a single photon using holographic techniques. An image of the UofR logo was cut into a stencil and a beam of laser light was passed through a beam splitter (classic holographic imaging technique); then a single photon from that beam was passed through the cut out portion of the stencil. Due to the nature of quantum mechanics, that photon passed through every region of the cut away part of the stencil (or at least, that's how …
