- Title
New circular quantum secret sharing for remote agents.
- Authors

- Abstract
This study presents a novel circular quantum secret sharing (QSS) protocol based on the controlled-NOT (CNOT) gate for remote agents. A CNOT gate is able to entangle a Bell state and several single photons to form a multi-particle GHZ state. Using this technique, the proposed QSS scheme is designed in purpose to be congenitally free from the Trojan horse attacks. Moreover, for each shared bit among n party, the qubit efficiency has reached $${\frac{1}{2n+1}}$$, which is the best among the current circular QSS's.
