Description

Single-particle entanglement requires at least two degrees of freedom for the particle that is used to make a nonfactorizable superposition. Using a two-slit experiment with horizontal and vertical polarizers over each slit, respectively, we illustrate how one measures at the slits to create an entangled state, followed by a delayed-choice placement of a second polarizer (before the photons hit the screen) to control the particle-like, or wave-like nature of the final observed pattern. This approach is used to teach (both non-scientists and undergraduates) the subtleties of entanglement and how delayed-choice experiments actually work.
