Seaworthy Quantum Key Distribution Design and Validation (SEAKEY)
Abstract
This is the SEAKEY final report for the BBN-RVS team for the Phase I reporting period, February 2014 through February 2015. Our tasks under this project include identifying key challenges to transition QKD to a naval environment and determination of optimum operating parameters for a naval QKD system, in pursuit of the Seakey end-of-program goal of achieving key rates of 1Mbit/sec at a range of 10-30 km in a naval environment. Program Highlights: 1. Fundamental upper bound to the key rate achievable using any QKD protocol over a lossy channel. 2. Developed a MATLAB tool for the evaluation of secret key rates under turbulent propagation (a theoretical model) and atmospheric absorption and scattering (a numerical model taken from MODTRAN), while employing a single spatial mode. 3. A quantitative trade study of using multiple spatial modes and finding up to how many spatial modes may yield a perceivable key rate benefit. 4. Development of a quantum-secure direct communication protocol with near-optimal rate-loss tradeoff that uses laser light modulation and homodyne detection, that is immune to a quantum-limited passive eavesdropper. 5. Identification of a potentially far-reduced-complexity high-rate CV KD protocol. This report is organized as follows: 1. This document (containing minor programmatic points, organizational notes and summary of progress in Phase I); 2. A PPTX document (SEAKEY_RESULTS_Y1) containing the summary presentation of Phase I; and 3. A folder (Model) containing the GUI m-file Input_parameters.m used to calculate key rates with inputs from the MODTRAN database.
