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 ...

A thumbnail-sized diamond chip just pulled off something that quantum physics says should be extraordinarily difficult: measuring three distinct properties of a microwave field in a single shot, at ...

How well can multiple incompatible observables be implemented by a single measurement? This is a fundamental problem in quantum mechanics with wide implications for the performance optimization of ...

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 ...
