Firstly, let me clarify that when I used the word "magic," I was using it in a colloquial sense to express the fact that quantum entanglement appears to defy classical intuitions. In reality, there is no magic involved, and we rely on rigorous mathematical models to describe and predict the behavior of entangled particles.
Now, to address your question about correlated states: when two particles are entangled, they become part of a single quantum system with a shared state. That means that the state of the entire system must be described by a single wave function that takes into account the possible states of each individual particle. When you measure one of the particles (let's call it A), the wave function "collapses" and the state of the other particle (B) becomes correlated or entangled with the measured state of A.
As for your third question, yes, if you change the spin of particle A, it immediately has an effect on particle B, regardless of the distance between them.
Finally, your fourth question touches on one of the most intriguing aspects of quantum entanglement. In quantum mechanics, measurements are inherently sensitive to the state of the system being measured. When you measure a particle, you are interacting with it in a way that inevitably changes its state. When two particles become entangled, their states become so highly correlated that measurements of one particle affect the state of the other particle. This phenomenon is sometimes described as "spooky action at a distance," and it remains a fascinating and active area of research in physics.
