The receiver includes a sharing unit, a key distilling unit, a data communication controller, and a calculator. The key sharing unit is configured to generate a shared bit string through quantum key distribution with each transmitter via a corresponding photon communication channel. The key distilling unit is configured to generate the cryptographic keys from the respective shared bit strings. The data communication controller is configured to receive from each transmitter first information about a corresponding cryptographic key via a corresponding data communication channel. The calculator is configured to calculate the photon timeslots based on at least the first information. The data communication controller is configured to transmit the photon timeslots to the transmitters."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Receiver, transmitter, communication system, and communication method","description":"According to an embodiment, a receiver is connected to transmitters through photon communication channels and data communication channels to generate identical cryptographic keys to be shared with eac","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9813237","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.
