Measurement-Induced Localization of an Ultracold Lattice Gas
Measurement-Induced Localization of an Ultracold Lattice Gas
The process of measurement can modify the state of a quantum system and its subsequent evolution. Here, we demonstrate the control of quantum tunneling in an ultracold lattice gas by the measurement backaction imposed by the act of imaging the atoms, i.e., light scattering. By varying the rate of light …
