About the Delayed-Choige Experiment

  • Philip R. Wallace

Abstract

In the so-called “delayed-choice” experiment, a beam of photons is split by a half-silvered mirror, so that parts of it can go by two different routes. After reflection, the two halves of the beam can be recombined by a second such mirror, and interference is observed. We are then asked to imagine that the second mirror is not inserted until the photons have already accomplished their travel, or after they have chosen one path or the other.
