New Frontier for Quantum Sensing

Facebook X LinkedIn Email
Devices that harness the counterintuitive features of quantum mechanics could signal the start of a second quantum revolution.

MARIE FREEBODY, CONTRIBUTING EDITOR, [email protected]

Quantum physics is a peculiar field. In the subatomic domain, the usual physical laws no longer apply. Instead, nonintuitive behaviors reign and new laws govern. A case in point is the Heisenberg uncertainty principle, which tells us that it is not possible to know both the exact position and the exact momentum of an object at any one time. Quantum mechanics ­— an idea that started with Planck, Einstein and Heisenberg more than 100 years ago — gave us a better understanding of

Glossary
quantum sensing
Quantum sensing refers to a class of sensing technologies that leverage principles from quantum mechanics to enhance the precision and sensitivity of measurements. Traditional sensors operate based on classical physics, but quantum sensing exploits quantum properties, such as superposition and entanglement, to achieve improved performance in terms of accuracy, resolution, and sensitivity. Key concepts and characteristics of quantum sensing include: Superposition: Quantum sensors can...
