Asymmetric node placement in fiber-based quantum networks

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Guus Avis, Robert Knegjens, Anders S. Sørensen, Stephanie Wehner, | Summary: Restrictions imposed by existing infrastructure can make it hard to ensure an even spacing between the nodes of future fiber-based quantum networks. We here investigate the negative effects of asymmetric node placement by considering separately the […]
