Putting hypersensitive quantum sensors in a living cell is a promising path for tracking cell growth and diagnosing diseases -- even cancers -- in their early stages. Many of the best, most powerful ...

Quantum sensing has long promised exquisite sensitivity, but in the real world, environmental noise usually buries the very signals researchers want to see. A new experiment using just three trapped ...

We’re probably all familiar with the Hall Effect, at least to the extent that it can be used to make solid-state sensors for magnetic fields. It’s a cool bit of applied physics, but there are other ...

Forbes contributors publish independent expert analyses and insights. Paul-Smith Goodson is an analyst covering quantum computing and AI. Satellite GPS is a vital navigation technology designed for ...
