Quantum secret sharing protocol using modulated doubly entangled photons

In this paper, we propose a quantum secret sharing protocolutilizing polarization modulated doubly entangled photon pairs. Themeasurement devices are constructed. By modulating the polarizationsof entangled photons, the boss could encode secret information onthe initial state and share the photons with different members torealize the secret sharing process. This protocol shows the securityagainst intercept-resend attack and dishonest member cheating. Thegeneralized quantum secret sharing protocol is also discussed.
