KentuckyFC writes "The human eye is a good photon detector--it's sensitive enough to spot photons in handfuls. So what if you swapped a standard photon detector with a human eye in the ongoing experiments to measure spooky-action-at-a-distance? (That's the ability of entangled photons to influence each other, no matter how far apart they might be.) A team of physicists in Switzerland have worked out the details and say that in principle there is no reason why human eyes couldn't do this kind of experiment. That would be cool because it would ensure that the two human observers involved in the test would become entangled, albeit for a short period time. The team, led by Nic Gisin, a world leader on entanglement, says it is actively pursuing this goal (abstract) so we could have the first humans to experience entanglement within months."
