Why Quantum Information is Never Destroyed
Summary
This episode explores why conservation of information is a fundamental requirement of quantum mechanics, linking it to time reversal symmetry and the principle of unitarity. The host explains how the Schrödinger equation ensures that distinct quantum states cannot merge, thereby preserving probability and preventing information loss. The discussion contrasts this with the Copenhagen interpretation, which breaks time reversibility, while noting that other interpretations like Many Worlds maintain it.
