"true entanglement requires trust that lasers/ detectors calibrated preventing security holes, overcome using 3 sources arranged in triangle, each source sends photon to 2 of 3 observers/ also uses Elegant Bell Inequality to prove entanglement... verifies security purely through data itself... compatible with 40 million photon/ second broadband emitters recently developed, creating path toward high-speed quantum data... highly scalable due to modular architecture"
