Observation of Non-Hermitian Skin Effect in Acoustic Metamaterials
Journal of Quantum Physics
- Volume 26, Issue 3 — September 2023 (2023)
- Research Article
Author
We experimentally realize the non-Hermitian skin effect in a 1D acoustic metamaterial with engineered gain and loss. The bulk-boundary correspondence breakdown is characterized by eigenvalue winding numbers and localization lengths.…

Quantum Error Correction on Superconducting Processors: A Short Communication
Journal of Quantum Physics
- Volume 27, Issue 1 — February 2024 (2024)
- Short Communication
Author
We benchmark surface code and repetition code implementations on 5 commercial superconducting quantum processors. Logical error rates per cycle range from 3.1e-3 to 8.7e-3, with threshold fidelities between 98.4-99.2%. Gate…

- Research Article
Author
Corresponding Author
We report experimental evidence of topological superconductivity in InAs/Al hybrid nanowires with epitaxial interfaces. Tunneling conductance spectroscopy reveals zero-bias peaks consistent with Majorana zero modes persisting over a 200 mT…
