Drama over quantum computing’s future heats up
Physicists continue to argue over Microsoft’s qubit claims. The entire field hangs in a delicate balance.
The controversy centers on Microsoft’s February claim that it had built a new type of quantum hardware — a topological qubit, made from a pattern of electrons on a tiny wire. But in the journal article accompanying the release, the editors wrote that Microsoft had not conclusively shown the electrons forming the signature pattern, known as Majorana zero modes. That’s why experts predict that an early useful application of quantum computers could be performing accurate and fast chemistry simulations, for discovering new materials for better batteries, more climate-friendly fertilizers, and new medical drugs.
