“Two entangled particles are linked in such a way that the state of one of them determines the state of the other. Have you ever heard how identical twins say they can tell when the other one has been hurt? I’ve no idea how true this is for humans but with particles, that’s kind of what entanglement is like.”
Podcast “Sparkly and Spooky”
“Measurements of physical properties such as position, momentum, spin, polarization, etc. performed on entangled particles are found to be appropriately correlated. For example, if a pair of particles is generated in such a way that their total spin is known to be zero, and one particle is found to have clockwise spin on a certain axis, then the spin of the other particle, measured on the same axis, will be found to be counterclockwise.”
