Scientists have developed a next-generation version of the charge-coupled device, or CCD, that’s in your home camera. This sensitive, new technology, the skipper CCD, has the potential to exploit the quantum nature of light to capture images of objects with exceptional resolution. Thanks to the technology’s heightened sensitivity, the skipper CCD could image objects one photon at a time, increasing the clarity of the signal in quantum imaging experiments. Scientists are designing a skipper-CCD optimized for such an application. They’re also exploring the quantum entanglement of photons as a tool to look for dark photons, a hypothetical particle related to dark matter.
Caltech and Lawrence Berkeley National Laboratory are partners on this initiative.
