Quantum entanglement and classical correlation are both ways in which two particles can be correlated with each other, but they differ in their degree of correlation and their properties. Classical correlation exists between two particles when there is a statistical correlation between their states, but their states are not dependent on each other. In contrast, entanglement exists between two particles when their states are dependent on each other, even if the particles are separated by large distances. This dependence allows for the potential for non-local effects and has no classical counterpart.\n
