Abstract
Methods and systems for performing secure quantum key distribution (QKD) over noisy channels are disclosed. A first computing device generates a challenge set using a secret seed, applies the challenges to its CRP, and receives an ordered set n responses, where n has the same number of bits as the key. It then sends only those responses in positions that correspond to 1s in the key to the second computing device. Those responses are sent under a QKD protocol such as BB84. The second computing device generates the same challenges and recovers the same responses with a mirror CRP mechanism. It also receives the subset of responses from the first computing device. Generated responses that match received responses correspond to 1s in the key, and 0s are assigned to all other positions.
