String of Trapped Ions (IMAGE) University of Innsbruck Caption The image visualizes a string of trapped ions that start interacting with each other. A complex many-particle quantum state (psi)emerges as a result of these interactions. The state can be reconstructed by carrying out measurements on groups of neighboring ions.
