Introduction to quantum mechanics

How can two particles instantly affect each other across vast distances?

Imagine you have two entangled particles. If you measure the state of one particle, the other particle's state instantly changes, no matter how far apart they are.

It's like having two magic dice that always land on the same number when rolled, even if they're in different cities. The technical term for this is "quantum entanglement."

Example

If you roll a magic die in New York and get a 4, then roll the other die in Los Angeles, it will also show a 4 instantly.

Remember this

Quantum entanglement shows that particles can be connected in such a way that the state of one instantly influences the state of another, regardless of distance.
