    "abstract": "The ladder proof of nonlocality without inequalities for two spin half\nparticles proposed by Hardy et al. (Phys. Rev. Lett. 79 (1997) 2755) works only\nfor nonmaximally entangled states and goes through for 50% of pairs at the\nmost. A similar ladder proof for two spin-1 particles in a maximally entangled\nstate is presented. In its simplest form, the proof goes through for 17% of\npairs. An extended version works for 100% of pairs. The proof can be extended\nto any maximally entangled state of two spin-s particles (with s equal or\ngreater than 1).",
