These properties allow quantum computers to process more information than conventional bits that can only be in a single state and only act independently from each other. The magnets and microwaves together allow scientists to control the qubit. Scientists are getting better at detecting these errors, but correcting for them is still extremely difficult, Blakestad says. They thought hexagonal boron nitride, which is from a family known as van der Waals materials also called 2D materials , would be a good candidate to build a capacitor. So scientists and engineers like Hong are shouldering the responsibility of building a better qubit. Clearing the way toward robust quantum computing. Most Popular. Credit: Yang H.
