Abstract:

The form of Bell's inequality does not sufficiently measure quantum correlations because there are states that do not violate the inequality, but can be purified by a combination of local interactions and classical communications to yield a state that does not violate the inequality. It is possible to say that a quantum state is entangled or not, but the amount of entanglement cannot easily be determined for general mixed states. Any measure of entanglement has to satisfy specified conditions on the basis of quantum optics before constructing a whole class of good entanglement measures that are geometrically intuitive.
