Quantum sensing covers motion – including acceleration, rotation and gravity – electric and magnetic fields, and imaging. The benefits to quantum sensing include: Measuring electric and magnetic fields very accurately across many frequencies.[1]

Figure1: Scientists create quantum sensor that covers entire radio frequency spectrum

Figure1 shows a modern quantum sensor will measure the entire range of radio frequency and real-world signals, unlocking new technologies for strategic communication, spectrum knowledge, and electronic warfare. Army engineers have developed a quantum sensor that can sample radio frequency spectrum from zero to 20 GHz and track AM and FM radio, Bluetooth, Wi-Fi, and other communication signals.[2]

Benefits of Technology:

Frequency measurements based on variational quantum calculations on their ion trap quantum computer. Because the interactions used in linear ion traps are still relatively easy to simulate on classical computers. Similar to machine learning, the programmable quantum computer finds its optimal mode autonomously as a high-precision sensor. It possible to demonstrate the advantage of quantum technologies over classical computers on a problem of practical relevance.

The use of quantum science in sensors and sensing brings a set of tools that can promise greater sensitivity and accuracy than conventional technologies, some of which are already in use. However, to make the next leap to other practical applications outside of the lab, a combination of fundamental science research and engineering will be needed to realize functional and robust sensor systems. Broader applications would include quantum accelerometers, gyroscopes, and clocks that can provide accurate navigation solutions without the need for GPS.[3]
