The Effects of the Local Environment on a Compact Radio Interferometer I: Cross-coupling in the Tianlai Dish Pathfinder Array

Posted by dbos Chicago

Kavli Affiliate: Albert Stebbins | First 5 Authors: Juhun Kwak, John Podczerwinski, Peter Timbie, Réza Ansari, John Marriner | Summary: The visibilities measured by radio astronomical interferometers include non-astronomical correlated signals that arise from the local environment of the array. These correlated signals are especially important in compact arrays such as those under development for […]

Robust poor man’s Majorana zero modes using Yu-Shiba-Rusinov states

Posted by dbos Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Francesco Zatelli, David van Driel, Di Xu, Guanzhong Wang, Chun-Xiao Liu | Summary: The recent realization of a two-site Kitaev chain featuring "poor man’s Majorana" states demonstrates a path forward in the field of topological superconductivity. Harnessing the potential of these states for quantum information processing, however, […]

Exploring Active Learning in Meta-Learning: Enhancing Context Set Labeling

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Wonho Bae, Jing Wang, Danica J. Sutherland, , | Summary: Most meta-learning methods assume that the (very small) context set used to establish a new task at test time is passively provided. In some settings, however, it is feasible to actively select which points to label; the […]
