Phys. Rev. Lett. 91, 230403 (2003) [4 pages]Bell’s Theorem without Inequalities and without AlignmentsReceived 13 March 2003; published 2 December 2003 A proof of Bell’s theorem without inequalities is presented which exhibits three remarkable properties: (a) reduced local states are immune to collective decoherence; (b) distant local setups do not need to be aligned, since the required perfect correlations are achieved for any local rotation of the local setups; (c) local measurements require only individual measurements on the qubits. Indeed, it is shown that this proof is essentially the only one which fulfills (a), (b), and (c). © 2003 The American Physical Society URL:
