What does a photon carry from its parent particle that when it interacts with another particle, it entangles both the particles?

  • $\begingroup$ It depends what you mean by "entanglement" A photon carries energy/momentum and spin orientation. It can transfer this information to a particle it interacts witth, and the state of the second particle can give information about the state and energy level of the parent particle, for example. $\endgroup$ – anna v Feb 27 at 6:31
  • $\begingroup$ @annav suppose the entanglement found between the two particles after one shared photon with the other is spin-entanglement. $\endgroup$ – Viswa Vijeta Feb 27 at 7:55
