Necessary and sufficient detection efficiency for the Mermin inequalities
Adan Cabello, David Rodriguez, Ignacio Villanueva
We prove that the threshold detection efficiency for a loophole-free Bell experiment using an -qubit Greenberger-Horne-Zeilinger state and the correlations appearing in the -…
Experimental demonstration of a quantum protocol for Byzantine agreement and liar detection
Sascha Gaertner, Mohamed Bourennane, Christian Kurtsiefer +2
We introduce a new quantum protocol for solving detectable Byzantine agreement (also called detectable broadcast) between three parties, and also for solving the detectable liar de…
Mermin inequalities for perfect correlations
Adan Cabello, Otfried Gühne, David Rodriguez
Any n-qubit state with n independent perfect correlations is equivalent to a graph state. We present the optimal Bell inequalities for perfect correlations and maximal violation fo…
Bipartite all-versus-nothing proofs of Bell's theorem with single-qubit measurements
Adan Cabello, Pilar Moreno
If we distribute n qubits between two parties, which quantum pure states and distributions of qubits would allow all-versus-nothing (or Greenberger-Horne-Zeilinger-like) proofs of…
Six-qubit permutation-based decoherence-free orthogonal basis
Adan Cabello
There is a natural orthogonal basis of the 6-qubit decoherence-free (DF) space robust against collective noise. Interestingly, most of the basis states can be obtained from one ano…
Experimental quantum "Guess my Number" protocol using multiphoton entanglement
Jun Zhang, Xiao-Hui Bao, Teng-Yun Chen +3
We present an experimental demonstration of a modified version of the entanglement-assisted "Guess my Number" protocol for the reduction of communication complexity among three sep…
