$$|\psi\rangle = \frac1\sqrt2(|00\rangle + |11\rangle)$$
Entanglement has been experimentally verified in various systems, including photons, electrons, and atoms. One of the most notable experiments demonstrating entanglement is the EPR paradox, which involves measuring the correlation between the polarization of two entangled photons.

In quantum mechanics, entanglement is described using the mathematical framework of wave functions and operators. When two particles are entangled, their wave functions become correlated, resulting in a non-separable state. This means that the state of one particle cannot be described independently of the other, even when they are separated by large distances. their wave functions become correlated
