A “Mostly Equation-Free” Introduction to the Quantum Measurement Paradox

The Quantum Measurement Paradox (aka. the Quantum Measurement Problem) is one of the oldest unresolved paradoxes in quantum theory. Simply stated, the paradox is that there appears to be two sets of rules required to describe the evolution of a quantum system. Schrödinger’s equation can be used to describe an undisturbed quantum system that slowly changes in time. However, when a measurement of that system is performed, a very abrupt change occurs in the system which cannot be modeled using Schrödinger’s equation. Another set of rules is required to accurately describe the abrupt change. Why are two sets of rules required to describe our one reality? In this talk, I will briefly summarize the Quantum Measurement Paradox and then present some of the more promising attempts to resolve the paradox.
Anyone who has completed or is currently taking a course in Modern Physics (PHYS 213) should be able to easily comprehend the ideas presented. The talk will primarily focus on a conceptual understanding of the topic, and equations will be used very sparingly.
