This simulator implements  the Wheeler's Delayed Choice Experiment in an ideal Interferometer of Mach-Zehnder type, as desccribed by John Archibald Wheeler and Wojciech Hubert Zurek,  Editors in "Quantum Theory and Measurement" , Princeton Series in Physics, (1984).

The simulator shows  the basic fundamental  ideas of the Quantum Mechanics:

    Wave-Particle nature of Photon
    Probabilistic interpretation of  Quantum Mechanics
    Superposition of Quantum States in Beam Splitting
    Interference of states in One Photon experiments
    The striking difference between  Photons and Classical  
    particles, i.e. between Quantum Mechanics and Classical
    Common Sense intuitions

The simulator has a wide target range, from High School to Physics Undergraduate students.

WheelerDelayedExperiment.pdf  is a PDF file with the QM Background and the simulator use.

WheelerDelayed_1.mp4 is a video tutorial and User Guide.
