# Analysis and minimization of bending losses in discrete quantum networks

@article{Nikolopoulos2012AnalysisAM, title={Analysis and minimization of bending losses in discrete quantum networks}, author={Georgios M. Nikolopoulos and Anton{\'i}n Hoskovec and Igor Jex}, journal={Physical Review A}, year={2012}, volume={85} }

We study theoretically the transfer of quantum information along bends in two-dimensional discrete lattices. Our analysis shows that the fidelity of the transfer decreases considerably, as a result of interactions in the neighbourhood of the bend. It is also demonstrated that such losses can be controlled efficiently by the inclusion of a defect. The present results are of relevance to various physical implementations of quantum networks, where geometric imperfections with finite spatial extent…
