Researchers Stack Photons Using Quantum Entanglement Technique

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.
