However, such an approach may result in cross-mode coupling and detection complexities, thereby reducing quantum cryptography performance. This fundamental trade-off between correctness and secrecy motivates the search for new error-correction approaches to better exploit the advantages of high-dimensional encoding. Here, we introduce the method of reduced state embeddings to quantum key distribution (QKD): a k-dimensional signal set embedded in a d-dimensional Hilbert space, where k new | recent | 2025-10 References & Citations INSPIRE HEP NASA ADSGoogle Scholar Semantic Scholar export BibTeX citation Loading...
