The delayed-choice experiment concept began as a series of thought experiments in quantum physics, first proposed by Wheeler in 1978. [ 27 ] [ 28 ] According to the complementarity principle , the 'particle-like' (having exact location) or 'wave-like' (having frequency or amplitude) properties of a photon can be measured, but not both at the ...
A delayed-choice quantum eraser experiment, first performed by Yoon-Ho Kim, R. Yu, S. P. Kulik, Y. H. Shih and Marlan O. Scully, [1] and reported in early 1998, is an elaboration on the quantum eraser experiment that incorporates concepts considered in John Archibald Wheeler's delayed-choice experiment.
As inspirations, the paper mentions Eugene Wigner's focus on the measurement problem, conversations with Willis Lamb, and John Archibald Wheeler's thought experiments. The paper also points out that the experiment could be run in delayed choice mode , as conceptualized by Wheeler's thought experiments, what is now known as a delayed-choice ...
Physicists have found that observation of quantum phenomena by a detector or an instrument can change the measured results of this experiment. Despite the "observer effect" in the double-slit experiment being caused by the presence of an electronic detector, the experiment's results have been interpreted by some to suggest that a conscious mind ...
Looking back on Wheeler's 10 years at Texas, many quantum information scientists now regard him, along with IBM's Rolf Landauer, as a grandfather of their field. That, however, was not because Wheeler produced seminal research papers on quantum information. He did not—with one major exception, his delayed-choice experiment.

In 1996, Tim Maudlin proposed a thought experiment involving Wheeler's delayed choice experiment that is generally taken as a refutation of TIQM. [14] However Kastner showed Maudlin's argument is not fatal for TIQM.
A diagram of Wheeler's delayed choice experiment, showing the principle of determining the path of the photon after it passes through the slit. Wheeler's delayed-choice experiments demonstrate that extracting "which path" information after a particle passes through the slits can seem to retroactively alter its previous behavior at the slits.
