A Symmetric Extensible Protocol for Quantum Secret Sharing

This paper introduces the Symmetric Extensible Quantum Secret Sharing protocol, a novel quantum protocol for secret sharing. At its heart, it is an entanglement-based that relies on use of maximally entangled GHZ tuples, evenly distributed among players, endowing spymaster with ability to securely share message agents. Its security stems from fact highly improbable malicious eavesdropper or rogue double agent disrupt successful execution. It characterized by symmetry, since all agents are treated indiscriminately, utilizing identical circuits. Furthermore, can be seamlessly extended arbitrary number Finally, after completion part will have publicly transmit some information, in order allow unlock message. considered as additional advantage, due gives privilege deciding if, when, right time message, protocol.
