Phys. Rev. Lett. 101, 080501 (2008) [4 pages]Error Correcting Bell InequalitiesReceived 14 March 2008; published 18 August 2008 Quantum error-correcting codes can protect multipartite quantum states from errors on some limited number of their subsystems (usually qubits). We construct a family of Bell inequalities which inherit this property from the underlying code and exhibit the violation of local realism, without any quantum information processing (except for the creation of an entangled state). This family shows no reduction in the size of the violation of local realism for arbitrary errors on a limited number of qubits. Our minimal construction requires preparing an 11-qubit entangled state. © 2008 The American Physical Society URL:
