Quantum Entanglement Used to Stack Light Particles ScienceDaily 2010-02-15
While many of us enjoyed constructing little houses out of toy bricks when we were kids, this task is much more difficult if bricks are elementary particles. It is even harder if these are particles of light -- photons, which can only exist while flying at an incredible speed and vanish if they touch anything.
A team at the University of Calgary has accomplished exactly that: by manipulating a mysterious quantum property of light known as entanglement, they are able to mount up to two photons on top of one another to construct a variety of quantum states of light -- that is, build two-story quantum toy houses of any style and architecture.
