Phys.org  December 16, 2022 Hybrid semiconductor–superconductor devices hold great promise for realizing topological quantum computing with Majorana zero modes. However, multiple claims of Majorana detection, based on either tunnelling or Coulomb blockade (CB) spectroscopy, remain disputed. An international team of researchers (Austria, USA – Princeton University, Spain) devised an experimental protocol that allowed them to perform both types of measurement on the same hybrid island by adjusting its charging energy via tunable junctions to the normal leads. This method reduces ambiguities of Majorana detections by checking the consistency between CB spectroscopy and zero-bias peaks in non-blockaded transport. They observed junction-dependent, […]
