Title: Entanglement-Enabled Delayed-Choice Experiment.
Authors: Kaiser, Florian, Coudreau, Thomas, Milman, Pérola, Ostrowsky, Daniel B., Tanzilli, Sébastien
Source: Science (pre-March 2025). 11/2/2012, Vol. 338 Issue 6107, p637-640. 4p.
Subjects: Physics experiments, Complementarity (Physics), Quantum theory, Wave-particle duality, Physics -- Methodology, Interferometry
Abstract: The article discusses a delayed-choice experiment for the measurement of wave-particle complementarity in quantum systems. The authors performed the experiments using a Mach-Zehnder interferomefer in which the output beam splitter was inserted or removed after a photon had entered the device. Topics include how the experiment's design allows the authors to continuously change the tested photon's behavior from wave-like to particle-like, thus illustrating the inadequacy of a naive wave or particle description of light, the ability of a single quantum object to behavior as a wave or particle, and Bohr's complementarity principle, which states that how a quantum object acts depends on the measurement apparatus.
