K1 Quantum Key Distribution (QKD)
AB Quantum Key Distribution (QKD) is a technique that provides perfect secrecy forcommunication systems, which is crucial against quantum computers capable ofbreaking current public-key cryptosystems. QKD is becoming a mature technologybut it still suffers from implementation problems due to imperfections on real hardwarethat soften it’s security. To correct those is necessary to develop error mitigationmechanisms, as well as security by design through use of two-photon protocols.In this Thesis, we combine these two approaches in fiber-based QKD, particularizingfor evolved fibers with improved data bandwidths. At the same time, we emphasizeintegration with quantum photonics, and carry out actual microfabrication of basicelements in the laboratory for future QKD applications.
