Quantum Sensing Applications

Current density and microwave emission

Our cutting-edge quantum sensing technology captures magnetic stray fields produced by current flowing through devices with unmatched sensitivity. This enables precise measurement of local current density at the nanoscale. Furthermore, the ProteusQ can quantitatively image microwave emissions from interconnects and antennas.

Current measurements

Nanoconfined Microwaves imaged by Rabi Oscillation Mapping

Swastik Kar’s group at Northeastern University used AC magnetometry on the Qnami ProteusQ to show that a permalloy nanowire can be used to concentrate RF fields into sub 300nm regions.

Current Flow Mapping in Ferroelectric Domain Walls

In a recent study on conducting ferroelectric domain walls, researchers used scanning NV magnetometry to directly visualize current flow at the nanoscale. These measurements were performed using the Qnami ProteusQ. The results challenge previous assumptions about current distribution […]
