The ability to recognize a target source and segregate it from a complex mixture of sounds is a requisite skill for sensory perception in realistic cluttered environments. The ease with which humans ...

Nonlinear optics has long relied on high-power lasers, whose spatial and temporal coherence ensures efficient nonlinear frequency conversion. However, a new study challenges the traditional assumption ...

The first electrically pumped random lasers for mid-infrared radiation are set to enable applications in sensing and imaging. Developed at A*STAR, the first electrically pumped random lasers for ...

(Nanowerk News) Researchers from MIT and elsewhere have recorded, for the first time, the "temporal coherence" of a graphene qubit -- meaning how long it can maintain a special state that allows it to ...
