This changes everything we thought we knew about building real unstoppable quantum machines.
🚨 A new superconductor just broke the rulebook
PtBiâ‚‚ only becomes superconducting on its surfaces, while the interior stays metallic. Even stranger, electrons refuse to pair along six specific directions, a pattern never seen before

A pair of Majorana particles acts as a single electron, but individually they behave very differently. This concept of ‘split electrons’ is the foundation for topological quantum computing, which aims to build more stable qubits. The separation of Majorana particle pairs protects them against noise and errors.
Now that PtBi₂’s unique superconductivity and related Majorana particles have been found, a next step is to control them. For example, thinning the material down will change the non-superconducting ‘sandwich filling’, potentially turning it from a conducting metal into an insulator. This also means that the non-superconducting electrons cannot interfere with the use of the Majoranas as qubits. Alternatively, applying a magnetic field will shift the electron energy levels, and could, for example, cause the Majorana particles to move from the edges to the corners of the material.
