Extremely precise quantum sensors promise to be a transformative technology with a variety of potential applications. For example, quantum sensors could advance neuroimaging by allowing researchers to detect nanoscale changes in electromagnetic fields in the brain with incredible precision.
This technology harnesses unique attributes of quantum mechanics, which describes the behavior of atoms and subatomic particles.
“At the heart of how these quantum sensors work is the interaction between discrete electronic energy levels of quantum systems and their environment,” says Jennifer Choy, who joined the Department of Engineering Physics as an assistant professor in January 2019. “We’re essentially using these interactions to precisely and sensitively measure physical quantities such as electric and magnetic fields, and inertial motion.” Read more here.
