Superposition states and mixed states

Superposition states and mixed states

The Superposition states and mixed states simulation allows students to use a Stern-Gerlach apparatus that can be oriented along two orthogonal axes to investigate whether they can experimentally distinguish mixed states from superposition states. Students can choose between different input spin states, which include a superposition state and a corresponding mixed state and two unknown input states labelled with question marks. The simulation shows the individual spin measurement outcomes and the measurement outcome probabilities mathematically and graphically. An accompanying activity for this simulation is available at http://quantumphysics.iop.org and www.st-andrews.ac.uk/physics/quvis. The simulation can be downloaded from the QuVis website www.st-andrews.ac.uk/physics/quvis. This... Show More
