About this Item
FIRST EDITION IN ORIGINAL WRAPS OF TWO (withbound) PAPERS RELATED TO WHEELER'S DELAYED CHOICE EXPERIMENT, THESE DEMONSTRATING THE "ULTIMATE" DELAYED CHOICE EXPERIMENT IN WHICH THE CHOICE IS DELAYED UNTIL AFTER THE MEASUREMENT IS MADE. These papers appear in the same November 2, 2012 issue of Science and describe "sophisticated demonstrations of the wave-particle duality of single quanta" (Wikipedia). Both also describe Wheeler delayed choice experiments in which the choice about which path the photon takes is made AFTER the measurement is made. The Peruzzo et al., paper "uses Bell inequalities to replace the delayed choice devices, but it achieves the same experimental purpose in an elegant and convincing way" (Wikipedia). The fourth, by Kaiser et al., specifically notes that "wave and particle behavior can coexist simultaneously" (Kaiser, 2012). The result "underlines the fact that a simple vision of light as a classical wave or a particle is inadequate" (ibid). In 1978, Einstein's last collaborator John Wheeler conducted a milestone thought experiment that has come to be known as Wheeler's delayed choice experiment. Wheeler's paper has generated many subsequent quantum experiments, among them the one offered here. In Wheeler's 1978 experiment, "a single photon has two paths it could take in an interferometer. In its wave character, the photon will take both paths simultaneously. In its particle character, the photon needs to decide which of the two paths it will take. Wheeler proved, in accordance with quantum mechanics, that the decision whether the photon will behave as a wave or as a particle can be [made] even after it has already entered the interferometer" (Science News, January 9, 2013). NOTE: We separately a number of other important works on delayed choice quantum experiments: (1) "Experimental Realization of Wheeler's Delayed-Choice Gedanken Experiment" by Alain Aspect, Philippe Grangier, Jean-François Roch, et al. (Science 315 No. 5814 pp. 966-968, February 6, 2007). (2) "Quantum-enhanced Positioning and Clock Sychronization" (Nature, 412, pp. 417-419, July 26, 2001).
