N-particle N-level singlet states: Some properties and applications
arXiv:quant-ph/0203119 · doi:10.1103/PhysRevLett.89.100402
Abstract
Three apparently unrelated problems which have no solution using classical tools are described: the "N-strangers," "secret sharing," and "liar detection" problems. A solution for each of them is proposed. Common to all three solutions is the use of quantum states of total spin zero of N spin-(N-1)/2 particles.
