Majorana qubits could be error resistant. But after a contentious talk at the Global Physics Summit, scientists aren’t convinced Microsoft has them.

Topological insulators are strange stuff – the bulk of this material is insulating and cannot carry an electrical current, yet the surfaces of the same material are conducting. This means that charged ...

Topological materials can be categorized into several types, including topological insulators, topological superconductors, and topological semimetals. Each type exhibits unique electronic properties ...

Yesterday, three members of Microsoft’s quantum team presented their work towards a topological quantum computer at the APS Global Summit in Anaheim. Last month, the team made waves announcing ...

But not just any quasiparticle will do. For topological quantum computing, Majorana particles—more specifically Majorana zero ...

When introduced into a nematic liquid crystal, these particles induce three-dimensional director fields and topological defects dictated by colloidal topology. While electric fields, photothermal ...

The solution was made possible by utilizing a special technology known as magnetic topological insulator Hall-bar devices. This latest invention addresses a major challenge concerning the ...

While the more recent paper describes the structure and architecture that could be used to build a topological quantum computer, Microsoft "cannot show" it can "really operate it," Jelena Klinovaja, a ...

I caught up with Nayak after his talk and asked him about the challenges of achieving Microsoft’s goal of a superconductor-based topological qubit. That conversation is the first segment of today’s ...
