Abstract
Quantum secure authentication (QSA) is a novel authentication technique to prevent replicating a physical key and digital-emulating by an unauthorized access. We have been developing the QSA system using deformable mirrors. Thanks to an efficient optical setup and adaptive optics methods, a system experiment of the QSA was successfully demonstrated with an error probability of 3.7×10-3.
