  We demonstrate a multipartite protocol to securely distribute and reconstruct
a quantum state. A secret quantum state is encoded into a tripartite entangled
state and distributed to three players. Any two of the three players are able
to reconstruct the state, whilst individual players obtain nothing. We
characterize this (2,3) threshold quantum state sharing scheme in terms of
fidelity, signal transfer and reconstruction noise. We demonstrate a fidelity
averaged over all reconstruction permutations of 0.73, which is achievable only
using quantum resources.
