“The thing you call the ‘quark’ might have quark-antiquark pairs and glue and all the rest built into it,”

"In a complicated setup that involved pairs of photons and hundreds of very accurate measurements, the team showed that the wave function must be real: not enough information could be gained about the polarisation of the photons to imply they were in particular states before measurement.
There are a few ways to save the epistemic view, the team says, but they invite other exotic interpretations. Killing the wave function could mean leaving open the door to many interacting worlds and retrocausality – the idea that things that happen in the future can influence the past."

"Thus one decides the photon shall have come by one route or by both routes after it has already done its travel."

"Within a naïve classical word view, quantum mechanics can even mimic an influence of future actions on past events," says Anton Zeilinger.
