Practical Framework for Analyzing High-Dimensional Quantum Key Distribution Setups

Author(s): Florian Kanitschar and Marcus Huber High-dimensional (HD) entanglement promises both enhanced key rates and overcoming obstacles faced by modern-day quantum communication. However, modern convex optimization-based security arguments are limited by computational constraints; thus, accessible dimensions are far exceeded by progress in H… [Phys. Rev.
