Abstract
Gao (2009 Commun. Theor. Phys. 52 421–4) has proposed an efficient multiparty quantum secret sharing (MQSS) with two-photon three-dimensional Einstein–Podolsky–Rosen (EPR) pairs. This work shows that a similar idea can also be used to construct an MQSS using the Greenberger–Horne–Zeilinger (GHZ) states. Compared to other MQSSs using GHZ-related states, the newly proposed protocol is more efficient in the aspect of qubit utilization.
