In this lecture I will use quantum computing to explore the implications of quantum measurement, and whether or not observing a quantum system causes it to irreversibly collapse into a single state. I will use the Schroedinger's cat, double-slit and Wigner's friend thought experiments to explore these ideas, presenting them as quantum circuits that can be implemented on quantum computers. The audience will gain a fundamental understanding of quantum measurement, its role in decoherence of quantum computers, and the historical origins of quantum computing. It will follow a similar approach to these thought experiments as that presented in the first part of my paper on quantum thought experiments as an educational tool. I'll provide some follow-up activity suggestions to explore the ideas of each lecture (probably based on my Quantum Paradoxes code tutorials for the associated topics in each one).
