Ternary Two Wavelength Quantum Key Distribution Protocol With Physical Unclonable Function Error Models and Eavesdropper Detection

This paper presents and studies the expected bit error rate (BER) of a prepare-and-measure quantum key distribution (QKD) protocol utilizing two wavelengths, ternary data, and a physical unclonable function (PUF). Models are developed as a function of channel and PUF noise, with and without eavesdropping, and then are subsequently validated through software simulations. At channel error rates below 30% and PUF error rates up to 10%, an eavesdropper presents a detectable error rate without Alice and Bob having to reveal a sample of their key.
