The peripheral device randomly phase shifts the second optical sub-pulse by a first phase, and the second peripheral device randomly phase shifts the first optical sub-pulse by a second phase. Furthermore, the optical path is such as to cause interference in the first optical beam splitter between the first and second optical sub-pulses, as a function of first and second phases."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Quantum cryptographic key distribution system including two peripheral devices and an optical source","description":"A quantum cryptographic key distribution system, including: an optical source, which generates a plurality of optical pulses; an optical beam splitter, which generates, starting from each optical puls","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9722784","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
