Yes, there is: the relative amplitudes of the terms in the entangled state. The only reason this doesn't appear in Bell's papers is that Bell assumed a particular entangled state (the singlet state) for which the ratio of amplitudes (or more precisely its squared modulus) is ##1## so it drops out of the formulas. But if we consider all possible entangled states of two qubits, the relative amplitudes of the terms in the particular entangled state we prepare will certainly contribute to the expectation value.DrChinese said:There is no variable from the entangled state (other than I guess a selection of type of conservation rule) that is a part of the quantum expectation value.
