P-4637 Practical Quantum Cryptography using Weak Measurements

Abstract

We propose to model the performance of a Quantum Key Distribution (QKD) system that utilizes weak measurements to secure the quantum channel. We aim to gain an understanding of the engineering requirements of such a QKD system, as compared to a conventional system based on the BB84 protocol. In addition, we propose to investigate the extension of weak measurement techniques to QKD methods that use higher dimensional discrete and continuous variable quantum states. The aim of this research is to provide a more intrinsically secure method of performing quantum key distribution so that practical QKD systems may attain higher security and better performance in terms of key rate and distance.
