Analysis of a High-Dimensional Extended B92 Protocol

Quantum key distribution (QKD) allows two parties to establish a shared secret that is secure against adversaries with unlimited computational power. One such protocol named B92 quite appealing due its simplicity but highly sensitive channel noise. In this work, we investigate high-dimensional variant of an extended version the and show it can distill over high noise channels. The consider requires Alice sends only three states Bob performs partial measurements. We perform information-theoretic security analysis our compare rate BB84 depolarization amplitude damping
