A special class of sensors leverages quantum properties to measure tiny signals at levels that would be impossible using classical sensors alone. Such quantum sensors are currently being used to study ...

In labs around the world, scientists chase forces too faint to see and too small to touch. They hunt for tiny magnetic signals that ripple across materials atom by atom. Those signals hold clues to ...

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 ...
