Abstract
Quantum Imaging Imaging an object is simply a case of collecting the light that is scattered from that object. However, if the object is embedded in or separated by a complex medium (tissue or atmosphere, for example), then the light is scattered, the wavefront of the light is muddled, and the image quality is reduced. Adaptive optics techniques use “guidestars” or “reference beacons” to undo the wavefront mixing and sharpen up the image. Kim and Englund show that nitrogen vacancy centers in diamond can be used as quantum reference beacons to enable superresolution focusing inside a scattering medium. The technique should be useful for quantum enhanced imaging and sensing applications. Science , this issue p. [528][1] [1]: /lookup/doi/10.1126/science.aar8609
