    • By "classical method" we are referring to all methods which employ calculations based on separable states. The Hartree-Fock method along with the concept of the Fermi surface are both examples of this type of reasoning. (The Fermi sea is expressible as a single Slater determinant so it can be considered to exhibit no quantum correlations [8-11]).

    • It should he noted that this interpretation is subject to the condition that Y is additive.

    • note
    • It is worth noting that the concurrence (and therefore the entanglement of formation) measures only two-party entanglement. It does not measure the many-party entanglement in states like the GHZ state (1/√2)(|↑↑↑〉+|↓↓↓〉), where the concurrence is zero for any pair of spins.
