Kavli Affiliate: Michael Wimmer | Summary:Protecting qubits from perturbations is a central challenge in quantum computing. Topological superconductors with separated Majorana bound states (MBSs) provide a strong form of protection that only depends on the locality of perturbations. While the link between MBS separation, robust degeneracy, and protected braiding is well understood in non-interacting systems, […]

Kavli Affiliate: Eliska Greplova | Summary:As quantum technology matures, the efficient benchmarking of quantum devices remains a key challenge. Although sample-efficient, information-theoretic benchmarking techniques have recently been proposed, there is still a gap in adapting these techniques to contemporary experiments. In this work, we re-formulate five of the most common randomized benchmarking techniques in the […]

Kavli Affiliate: Simon Groblacher | Summary:Weak quantum measurements enable real-time tracking and control of dynamical quantum systems, producing quantum trajectories — evolutions of the quantum state of the system conditioned on measurement outcomes. For classical systems, the accuracy of trajectories can be improved by incorporating future information, a procedure known as smoothing. Here we apply […]

Kavli Affiliate: Michael Wimmer| First 5 Authors: Thomas Wimmer, Thomas Wimmer, , , | Summary:We introduce AnyUp, a method for feature upsampling that can be applied to any vision feature at any resolution, without encoder-specific training. Existing learning-based upsamplers for features like DINO or CLIP need to be re-trained for every feature extractor and thus […]
