Abstract
The result of Wheeler's delayed choice experiment is a natural consequence of the entanglement of moving photons and particles (atoms, molecules) of the slit through which they move. The inclusion of quantum fields (taking into account that speed of virtual particles is not limited) self-consistently explains why interaction’s propagation velocity after closing one slit is larger than the speed of light.

One manifestation of entanglement is Wheeler’s delayed-choice experiment
Wheeler’s thought experiment [1] is a variant of an experiment using two static slits, in which one of the slits may be closed after a photon passes through both slits, but before the photon has reached the screen
How does a particle “know” that one of the slits was closed? How fast is the “knowing” communication? To answer these and other questions, a more detailed discussion of entanglement that explicitly takes into account the quantization of fields is required
Summary
One manifestation of entanglement is Wheeler’s delayed-choice experiment. Wheeler’s thought experiment [1] is a variant of an experiment using two static slits, in which one of the slits may be closed after a photon passes through both slits, but before the photon has reached the screen. 1. Introduction One manifestation of entanglement is Wheeler’s delayed-choice experiment. 2. Wheeler’s thought experiment and concepts of entanglement in quantum mechanics Currently Wheeler’s delayed-choice experiment has been experimentally implemented, in a somewhat different form (see, for example, [2,3,4,5]). If there are two slits, an interference pattern is observed on the screen (i.e., the photon demonstrates wave properties).
