The concept of measurement in quantum mechanics is a weak point in our current understanding of the universe. We have an accurate theory that predicts measurement outcome probabilities, as well as the state of a system immediately following measurement. However, the process of measurement is poorly understood and typically included as one of the postulates of quantum mechanics. In this work I propose an experiment, feasible with existing spin qubit technologies, that probes the time scales associated with the collapse of the state function thereby providing valuable insight into the quantum measurement process. In addition to providing guidance on how to think about the measurement process, the knowledge gained will likely impact state preparation and measurement protocols in quantum information science.
