Quantum Sensing

What is Quantum Sensing?

The modern world relies heavily on sensors to measure timing, acceleration, rotation, temperature, magnetic fields, electric fields, gravitational fields, and more. Many of today’s most precise sensors are expertly designed around classical physics principles. Quantum sensors aim to improve upon the performance of many modern sensors by taking advantage of quantum physics. These quantum sensors operate on an atomic level allowing for greater sensitivity and accuracy in several applications:

• Fundamental Physics Research

• Metrology

• Aerospace & Defense

• Material Science

• Life Science

Quantum Sensing Use Cases

Quantum sensing has many different use cases, but all of them require state-of-the-art R&D tools and measurement solutions.

Nitrogen-Vacancy Center

A nitrogen-vacancy center (NV Center) is a quantum sensor that can measure magnetic or electric fields for applications in aerospace & defense as well as biomedicine. This is made by exciting a nitrogen atom next to a vacant site in the crystal lattice, and then performing an optical read out with test and measurement equipment. 

Rydberg Atom

Another example is the Rydberg atom sensor. It is used for detecting electric fields across a wide frequency range from DC – THz. These quantum receivers are highly sensitive, making them an excellent sensor in this technology.

Photon Detector

Single photon detectors are a core component of many quantum sensing technologies. These incredibly sensitive receivers can detect photonic energy levels equivalent to that of a single photon.
