Quantum entanglement is the phenomenon of a group of particles being generated, interacting, or sharing spatial proximity in such a way that the quantum state of each particle of the group cannot be described independently of the state of the others, including when the particles are separated by a large distance.
Entanglement is at the heart of quantum physics and future quantum technologies. Like other aspects of quantum science, the phenomenon of entanglement reveals itself at very tiny, subatomic scales.
So if a beam with quanta in eigenstate A=1 is measured by the first analyzer it takes the A=1 channel. But when the second analyzer measures B, the state of each quanta is in a superposition of B-eigenstates and can take multiple channels. Each quanta collapses to different B-eigenstates.

Quantum entanglement occurs when a system of multiple particles in quantum mechanics interact in such a way so that the particles cannot be described as independent systems but only as one system as a whole.
