Description
The implementation of metropolitan-scale Memory-Assisted Measurement-Device-Independent Quantum Key Distribution (MA-MDI-QKD) stands as a crucial milestone on the pathway to global quantum secure communication. In this presentation, I will present a simplistic and intuitive stochastic model to predict key distribution rates in a MA-MDI-QKD scheme that addresses the real world parameters inherent to free-space quantum communication channels. Specific to my algorithm, the memory-assisted based system allows us to leverage the advantage of asynchronously loaded quantum memory when predicting the distribution rates. Specifically, by focusing on metropolitan distances, I will perform simulations tailored toward a system based on free-space links and field-deployable quantum memory. The model shown will predict key rate distributions over ranges of 10- 50 km for a set of atmospheric-based parameters and selection of QM efficiencies and coherence times. This tool provides impactful insights into the deployment and optimization of practical MA-MDI-QKD networks in urban environments. This streamlined approach is a valuable addition to existing quantum network simulators for the smooth integration of quantum networking into the field of communications engineering.
