Talk Title:  “Investigating the Quantum Measurement Process.”


In quantum mechanics the state of a system is described by the wave function. It is remarkable that according to the quantum theory the wave function changes with time in two seemingly distinct ways. There is a change in time which can be calculated from the time-dependent Schrodinger equation, and also the wave function is believed to change discontinuously as a result of measurements. However, despite much effort what constitutes a measurement and how a measurement causes a change in the wave function remains unclear. I will describe  experiments in which a part of the wave function of an electron is trapped in a box with walls sufficiently thick to prevent escape by tunneling.
