AI Technical Summary
Technical Problem
Existing quantum communication systems face challenges with fragile photon states, low key rates, and device-dependent security due to eavesdropping loopholes, especially in long-distance communications.
Method used
A method using multiphoton entanglement with coherent light beams for synchronization and phase compensation, combined with a Bell inequality test on beam splitters, ensures device-independent security and higher key generation rates, utilizing readily available components.
Benefits of technology
The method provides secure and efficient quantum key distribution with higher key rates, robust against losses, and guarantees security through device-independent physics-based verification.
