From: Security analysis of qutrit quantum secret sharing with linear optical correlation measurement
Secret key rates per sifted pulse under a depolarizing channel. The secret key rate of the three-party QSS protocol using qubits (black, dashed line) and that of the 3d-CQSS protocol (red, solid line) are drawn. p is the ratio of white noise. (a) The secret key rates when all the authorized parties are trusted. (b) The secret key rates when \(\hbox {Bob}_{{1}}\) cooperates with Eve.
