摘要
Supersinglets \S-N((d))] are states of total spin zero of N particles of d levels. Some applications of the \S-N((N))] and \S-N((2))] states are described. The \S-N((N)) ] states can be used to solve three problems that have no classical solution: The ' N strangers,' 'secret sharing,' and 'liar detection' problems. The \S-N((2))] (with N even) states can be used to encode qubits in decoherence-free subspaces.
