Stranger still, when two particles interact, they can become \u201centangled,\u201d shedding their individual probabilities and becoming components of a more complicated probability function that describes both particles together. This function might specify that two entangled photons are polarized in perpendicular directions, with some probability that photon A is vertically polarized and photon B is horizontally polarized, and some chance of the opposite. The two photons can travel light-years apart, but they remain linked: Measure photon A to be vertically polarized, and photon B instantaneously becomes horizontally polarized, even though B\u2019s state was unspecified a moment earlier and no signal has had time to travel between them.<\/p>\n<p><!-- Link: <a href=\"https:\/\/www.quantamagazine.org\/20170207-bell-test-quantum-loophole\/\">https:\/\/www.quantamagazine.org\/20170207-bell-test-quantum-loophole\/<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Quantum\u2019s natural selection explored.
