Quantum magnetometers breakthroughs promise ultimate precision sensors at room temperature using qubits and machine learning

A magnetometer is a device used to measure the direction and strength of the magnetic field at a particular location. Magnetometers are employed across several sectors such as energy, healthcare, aerospace & defense, consumer electronics, surveys, and industrial. A magnetometer is an instrument with a sensor that measures magnetic flux density B (in units of Tesla or As/ m2) at the point in space where the sensor is located. A magnetic field drops in intensity with the cube of the distance from the object. Therefore, the maximum distance that a given magnetometer can detect the object is directly proportional to the cube root of the magnetometer’s sensitivity. The sensitivity is commonly measured in Tesla.
