The return of the spin echo – Phys.org

A research team from Garching and Vienna discovered a remarkable echo effect that offers exciting new possibilities for working with quantum information.
Small particles can have an angular momentum that points in a certain directionthe spin. This spin can be manipulated by a magnetic field. This principle, for example, is the basic idea behind magnetic resonance imaging as used in hospitals. An international research team has now discovered a surprising effect in a system that is particularly …
