Researchers at Uppsala University in Sweden have identified how to distinguish between true and ‘fake’ Majorana states in one of the most commonly used experimental setups, by means of supercurrent measurements. Majorana states have exotic properties that make them promising candidates as qubits for fault-tolerant quantum computers. However, in experiments trivial zero-energy states mimicking Majorana states can also appear.
This theoretical study is a crucial step for advancing the field of topological superconductors and applications of Majorana states for robust quantum computers. (Uppsala University)
