Dirt. For millennia, the dark, rich soil underlying farms and gardens worldwide has been central to human survival. It’s also a lot more complex than it looks. Within every clump of soil lies an ...

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 ...

MIT researchers have created a quantum sensor that can measure multiple physical quantities at high-resolution. The sensor is made from so-called nitrogen-vacancy centers in diamonds, where a carbon ...
