This invention relates to secure transaction processing using quantum entanglement across multiple domains, supported by a photon transmission network.
Traditional cryptography (e.g., RSA) is vulnerable to quantum computing. Quantum key distribution (QKD) secures keys but not transactions directly. No known system combines entanglement verification with a scalable, multi-use network as described herein.
The Quantum Entanglement Transaction Security (QETS) system authenticates transactions via quantum entanglement. Entangled photons are generated, distributed through a scalable network, and verified at endpoints. Key features include quantum repeaters with multi-memory arrays, error correction, and broad applications (e.g., voting, IoT), offering a scalable, physics-based security solution.
Entanglement Generation Module: Uses spontaneous parametric down-conversion (SPDC) to produce entangled photon pairs at 1550 nm, with multi-wavelength multiplexing for high output (˜108 pairs/s).
End-User Verification Module: Photonic chips with SNSPDs and quantum error correction (e.g., surface codes).
Control System: AI-driven routing, pre-distribution to quantum memories.
A $1,000 online purchase: Payment processor distributes photons over 500 km via three repeaters. Seller verifies entanglement in 5 ms, completing the transaction.
