Majorana Quasiparticle Set to Help in Quantum Computing

The Majorana particle is a mysterious and one of the most thought-provoking pursuits in physics. Named after an Italian physicist Ettore Majorana, who first predicted the existence of such a particle back in 1937, it is now much closer to be controlled for quantum computing. The still widely unknown particle has one of the most unique properties. The foremost being its own nature as an antiparticle of it. A team of researchers at the Princeton are trying to study the particle. The group reports its various findings of the particle, the most important of which is about its source from different materials. The particle that has huge potential to be used for future quantum computing faces a serious challenge on how to manipulate it for the use.

The new study which was published this week in the journal named Science gives a report by the Princeton team over finding a way of controlling the Majorana quasiparticles in an environment that makes them even more strong. The environment comprises a superconductor and a topological insulator in a combination that makes the Majorana particles particularly resilient against getting destroyed by heat or from vibrations outside of the setting. The team also displayed a process to turn the particles on or off when brought near tiny magnets embedded in the device.

Ali Yazdani, a Professor of Physics and a Senior Author of the study said, “With this new study we now have a new way to engineer Majorana quasiparticles in materials.” The professor also added, “We can verify their existence by imaging them and we can characterize their predicted properties.”

Majorana particles are unique because of the way they stay stable in an environment even after the matter and antimatter are brought close to each other. The particles interact weakly with their environment which is in contrast to other particles which react violently when their matter and antimatter are brought into close proximity. The unique nature of these particles helps in storing quantum information at the two different locations which facilitate their use in Majorana-based quantum computer.
