The argument about entanglement goes back to Einstein. The notorious EPR (Einstein/Podolsky/Rosen) thought experiment of 1935 demonstrated that if quantum mechanics was correct then the determination of the state of one quantum particle could instantaneously and over any distance determine the state of another particle. This was afterwards referred to as entanglement or quantum entanglement.

Bird migration may be facilitated by an ability to see and navigate the Earth’s magnetic field. The process is suggested as being started by light entering a bird’s eye. Light would excite two electrons of a molecule in the bird’s eye in such a way that one electron was moved to another molecule. However, the two electrons would remain quantum entangled despite being separated. This means that a change in the spin or magnetic orientation of one electron would immediately alter the spin of its entangled partner.
