    "abstract": "Supersinglets $|{\\cal S}_N^{(d)}\u003e$ are states of total spin zero of $N$\nparticles of $d$ levels. Some applications of the $|{\\cal S}_N^{(N)}\u003e$ and\n$|{\\cal S}_N^{(2)}\u003e$ states are described. The $|{\\cal S}_N^{(N)}\u003e$ states can\nbe used to solve three problems which have no classical solution: The \"$N$\nstrangers,\" \"secret sharing,\" and \"liar detection\" problems. The $|{\\cal\nS}_N^{(2)}\u003e$ (with $N$ even) states can be used to encode qubits in\ndecoherence-free subspaces.",
