Analogies between Quantum Theory and Relativity

February 8, 2008

Some aspects of measurement in quantum theory can be illuminated by analogies with relativity theory. For example, consider the classic double-slit experiment and a single photon which “measures” which slit a particle goes through. When one considers the particle-plus-photon system, the photon does not actually collapse the wave function so that it is localized in […]
