Quantum teleportation is a reasonably well-defined physical process, whereby a quantum state is transferred between two separated entities that already share an entangled state. It's been demonstrated experimentally, and applications have been dreamed up. My question is: does this phenomenon occur "naturally" at all? Or is it in the category of things that, to the best of our knowledge, have only ever happened as a result of human ingenuity?

(I leave open the question of how exact the state transfer should be. Examples where teleportation explains something interesting about a system's behaviour would be ideal.)

Quantum teleportation has been suggested to be possible to occur in photosynthetic reaction centers. https://doi.org/10.1007/BF03166259

And it could in principle be occuring all the time through photochemistry in biology. Though to no real purpose, however, a related purposeful effect is the avian compass which(is hypothesized) to operate through quantum effects.

And more recently teleportation was demonstrated in a small molecule photosynthetic mimic. https://doi.org/10.1038/s41557-019-0332-8

Sorry if there are paywalls.
