On Wednesday, Microsoft released an update on its efforts to build quantum computing hardware based on the physics of quasiparticles that have largely been the domain of theorists. The information coincides with the release of a paper in Nature that provides evidence that Microsoft's hardware can actually measure the behavior of a specific hypothesized quasiparticle.

Separately from that, the company announced that it has built hardware that uses these quasiparticles as the foundation for a new type of qubit, one that Microsoft is betting will allow it to overcome the advantages of companies that have been producing qubits for years.

The zero mode


Quasiparticles are collections of particles (and, in some cases, field lines) that can be described mathematically as if they were a single particle with properties that are distinct from their constituents. The best-known of these are probably the Cooper pairs that electrons form in superconducting materials.
