Sensing and Metrology

The realization of precisely controlled quantum systems localized to nanometer dimensions enables ultrahigh resolution sensing and imaging, down to single molecule and single atom scales. Solid state quantum bits display quantum coherence properties similar to cold atoms, but are naturally localized to lattice constant length scales, and can be integrated into complex devices.

Additionally, a new frontier of metrology involves exploiting quantum measurement schemes to achieve higher sensitivity than what is possible classically with the same number of resources. The preparation of such states is an active area of research in many physical systems.
