Abstract
A quantum mechanical measurement device is provided. A spin ensemble is provided. A first light source provides a first light at a first wavelength, wherein the first light source is positioned to provide light into the spin ensemble. A detector is positioned to detect light from the spin ensemble. A modulator modulates absorption of the first light from the first light source by the spin ensemble at a frequency greater than a Larmor frequency of the spin ensemble.
