Abstract

A (t, n) threshold quantum secret sharing scheme is proposed, in which the secret is a quantum state, and the dealer encodes the secret through the phase shift operation. The participants perform the phase shift operations on the quantum state according to their private keys, and any t out of the n participants can use the Lagrange interpolation to recover the original quantum state. Compared to the existing schemes, the proposed scheme is simpler and more efficient.
