The QM Measurement program displays the time evolution of the position-space wave function and can be used to simulate the quantum-mechanical measurements of energy, position, and/or momentum. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the qm_measurement.jar file will run the program if Java is installed. The default wave function is an equal-mix four-state superposition in the infinite square well. Additional states and other potential energy functions can be specified using the Display | Switch GUI menu item. QM Measurement is one of 18 Open Source Physics programs that model time-dependent quantum mechanics using an energy eigenstate expansion. Other programs provide additional visualizations. They can be found by searching ComPADRE for Open Source Physics, OSP, or Superposition.
