I would say consciousness is, this is a post I made earlier.
Scully and Drühl found that there is no interference pattern when which-path information is obtained, even if this information was obtained
without directly observing the original photon, but that if you somehow "erase" the which-path information, an interference pattern is again
observed.In the delayed choice quantum eraser discussed here, the pattern exists even if the which-path information is erased shortly later in time
than the signal photons hit the primary detector.
The non interference pattern is already on the screen before they erase the wich path info, yet when the experimenter checks the screen later, it
still shows an interference pattern.
How is that possible? It's only possible because after the fact, the wich path info is not available, so the pattern on the screen adapts to the
experimenter not knowing the wich path, even though it was available at the time the particles hit the screen.
The pattern on the screen adapts to human consciousness. How else would you explain it?
However, the interference pattern can only be seen retroactively once the idler photons have already been detected and the experimenter has
obtained information about them, with the interference pattern being seen when the experimenter looks at particular subsets of signal photons that
were matched with idlers that went to particular detectors.
They are saying that the interference pattern only shows itself after the experimenter knows if the wich path info is available or not, by looking if
the idlers were picked up by the detectors that are related to the wich path info not being known in this case.
You have to have an understanding of the setup of the exp to understand this.
Why else would it matter what the experimenter knows, if human consciousness is not the deciding factor?
