A century after its conception, quantum mechanics still hold surprises that contradict many "common sense" notions. The contradiction is especially sharp in case one consider trajectories of truly objects such as single photons. From a classical point view, are well defined for particles, but not waves. wave-particle duality forces breakdown this dichotomy and resolves remarkable way: Trajectories can be defined, they utterly different from trajectories. Here, we give an operational...
