Quantum secret sharing with qudit graph states
arXiv:1004.4619 · doi:10.1103/PhysRevA.82.062315
Abstract
We present a unified formalism for threshold quantum secret sharing using graph states of systems with prime dimension. We construct protocols for three varieties of secret sharing: with classical and quantum secrets shared between parties over both classical and quantum channels.
