A framework called PQ-NeuroLink adds just 0.45 ms of p95 latency over an unsecured baseline in the most constrained Bluetooth Low Energy single-hop condition, while holding packet delivery at 99.0%. Wireless links between brain-computer interface devices have to be both secure and low-latency, and quantum computers threaten the cryptography they currently rely on. By separating authenticated session establishment from the symmetric streaming path, the framework offers a reproducible communication-layer foundation for secure next-generation BCI deployments.
