Preserving flying qubit in single-mode fiber with Knill Dynamical Decoupling (KDD)
ORAL
Abstract
The implementation of information-theoretic-crypto protocol is limited by decoherence caused by the birefringence of a single-mode fiber. We propose the Knill dynamical decoupling scheme, implemented using half-wave plates, to minimize decoherence and show that a fidelity greater than 96{\%} can be achieved even in presence of rotation error.
