QuTech researchers in Delft created a controlled system of three quantum dots that successfully demonstrated the properties of Majorana bound states—exotic quantum particles that could enable more stable quantum computing through their unique ability to be manipulated and moved between locations while maintaining resistance to errors.
A QuTech-led research team successfully created a three-site Kitaev chain in a hybrid InSb/Al nanowire that demonstrates enhanced stability of Majorana zero modes compared to two-site chains, marking significant progress toward scalable topological quantum computing.
A new way to combine two materials with special electrical properties — a monolayer superconductor and a topological insulator — provides the best platform to date to explore an unusual form of superconductivity called topological superconductivity. The combination could provide the basis for topological quantum computers that are more stable than their traditional counterparts.
