The Problem with Quantum Measurement

The Problem with Quantum Measurement

Today I want to explain why making a measurement in quantum theory is such a headache. I don’t mean that it is experimentally difficult, I mean that it is theoretically not understood just what is going on. And that is even though the problem is more than 100 years old. In this video I briefly go through the most important postulates of quantum mechanics, which is the Schrödinger equation, the Born rule, and the measurement postulate. I then explain why the measurement postulate is problematic and why re-interpreting it does not remove the problem.
