    "abstract": "We introduce a two-observer all-versus-nothing proof of Bell\u0027s theorem which\nreduces the number of required quantum predictions from 9 [A. Cabello, Phys.\nRev. Lett. 87, 010403 (2001); Z.-B. Chen et al., Phys. Rev. Lett. 90, 160408\n(2003)] to 4, provides a greater amount of evidence against local realism,\nreduces the detection efficiency requirements for a conclusive experimental\ntest of Bell\u0027s theorem, and leads to a Bell\u0027s inequality which resembles\nMermin\u0027s inequality for three observers [N. D. Mermin, Phys. Rev. Lett. 65,\n1838 (1990)] but requires only two observers.",
