“Shiba Glass” An Amorphous Topological Superconducting Surface May Lead To Easier Quantum Computing

Researchers from Aalto University Finland have developed for the first time, a method for creating amorphous topological superconducting materials that could drastically reduce the requirements for quantum computing.

Topological superconductors and insulators are priority amongst quantum physicists looking to create the next generation of supercomputers due to their lossless properties. Meaning that they do lose electrical or electromagnetic energy over time like ordinary devices.

Simply put – they are more energy efficiency.

However most topological materials proposed for quantum computing thus far have required pristine crystalline structures in order to sustain their uniquely superconductive states.

‘We have presented a method of fabricating topological materials in amorphous systems with randomly placed constituents. This means we can achieve superconductivity in the material by sprinkling magnetic atoms on a superconducting surface completely at random, not in highly-defined and ornamented lattices, for example,’ explains doctoral student Kim Pöyhönen.

‘Getting highly irregular, random systems to work as topological superconductors will potentially make their fabrication and manufacture much more convenient compared to current methods,’ says research group leader, Docent Teemu Ojanen.

For now the amorphous material is still in it’s experimental stages though we can expect that it will be a game charger for opening access to these super computers once it finally does break on to the scene.
