Question

From everything I've read about quantum mechanics and quantum entanglement phenomena, it's not obvious to me why quantum entanglement is considered to be an active link. That is, it's stated every time that measurement of one particle affects the other.

In my head, there is a less magic explanation: the entangling measurement affects both particles in a way which makes their states identical, though unknown. In this case measuring one particle will reveal information about state of the other, but without a magical instant modification of remote entangled particle.

Obviously, I'm not the only one who had this idea. What are the problems associated with this view, and why is the magic view preferred?

Answer 1

Quantum entanglement is considered to be an active link because measuring one particle instantly affects the state of the other particle, regardless of the distance between them. The magical view of quantum entanglement is preferred because it accurately describes the strange and non-intuitive phenomena observed in quantum mechanics.

Step-by-step explanation:

Quantum entanglement is considered to be an active link because it involves a correlation between the properties of two particles that cannot be explained by classical physics. When two particles are entangled, their states become intertwined and measuring one particle instantly affects the state of the other particle, regardless of the distance between them. This has been experimentally verified through various tests, such as the Bell's theorem experiment. The magical view of quantum entanglement is preferred because it accurately describes the strange and non-intuitive phenomena observed in quantum mechanics.
