“…Additionally, when two properties are related by the Heisenberg uncertainty principle, certainty in one of the properties results in uncertainty in the other, and vice versa. For example, knowing a photon's polarization in the rectilinear basis results in uncertainty of the photon's diagonal polarization state [8][9][10]. For security, this can mean that random, uncontrollable changes may be introduced into the QKD system by eavesdropper presence.…”

Multi-Wavelength Quantum Key Distribution Emulation with Physical Unclonable Function

et al. 2022

This work details the theory and implementation of a multi-wavelength quantum key distribution (QKD) emulation system with a physical unclonable function (PUF). Multi-wavelength QKD can eliminate the need to share a subsection of the final key for eavesdropper detection and allow for ternary and quaternary data transmission. The inclusion of the PUF adds an additional layer of security. We provide preliminary error analysis of our emulation system. To support this work, we introduce a bitwise transform operator that enables binary output of the PUF to satisfy the ternary and quaternary input requirements of the QKD system.
