Paper on Measurement-induced localization is published in Physical Review Letters

Sep. 2015

The act of observation has profound consequences on a quantum system. In this work, we experimentally demonstrate the famous 'Heisenberg microscope' and show the dramatic effect of continuous position measurements on the evolution of a quantum system. In particular, we confine nanoKelvin temperature atoms within an optical lattice and show that the act of imaging these atoms induces their localization, i.e. suppresses tunneling. In other words, we freeze the quantum motion of these atoms simply by the act of gazing at them.
