Converting Quantum Information (IMAGE) University of Warsaw, Faculty of Physics Caption A single photon -- a carrier of quantum information -- travels like a spinning coin, in a superposition of states. Modyfing its properties is extremely hard and should be done carefully, without destroying the superposition.
