Quantum entanglement is a physical phenomenon where pairs or groups of particles interact in ways such that the quantum state of each particle cannot be described independently of the state of the others.
In this simulation, you can entangle two particles and observe how measuring one instantly affects the other, no matter how far apart they are.
