Researchers at the University of Chicago ran electric current through a quantum dot surface and struck light. Infrared light.
The newfound ability to create infrared light using colloidal quantum dots could usher in a new era of cost-effective infrared lasers and sensors, significantly reducing manufacturing and operational costs.
Guyot-Sionnest remarked that this discovery stood as a prime example of the potential of quantum dots. “Many other applications could be achieved with other materials, but this architecture really only works because of the quantum mechanics,” he added.Efficient infrared light sources are needed for machine vision and molecular sensing.

Experimental quantum imaging distillation with undetected lightIt is possible to image an object with an induced coherence effect by making use of photon pairs to gain information on the item of interest—without detecting the light probing it. While one photon illuminates the object, its partner alone is detected, thereby preventing the measurements of coincidence events to reveal information of the sought after object. This method can be made resilient to noise, as well.
