High-dimensional quantum key distribution with resource-efficient
detection
High-dimensional encoding for quantum key distribution (QKD) enables increased achievable key rates and robustness as compared to the standard qubit-based systems. However, experimental implementations of such systems are more complicated, expensive, and require complex security analysis. In this work we present a proof of principle high-dimensional time-phase BB84 QKD experiment …
