A beautiful nanotech image

I regularly have blog posts that feature nanotech images, and sometimes I just run a nanotechnology image because it is so beautiful. This is one of those times

Quantum images

From KurzweilAI.net:

Physicists Produce Quantum-Entangled Images
PhysOrg.com, June 25, 2008

Researchers from the National Institute of Standards and Technology (NIST) and the University of Maryland (UM) have produced “quantum images,” pairs of information-rich visual patterns whose features are entangled (linked by the laws of quantum physics).


(NIST)

Matching up both quantum images and subtracting their fluctuations, their noise is lower (so their information content potentially higher) than it is from any two classical images.

In addition to promising better detection of faint objects and improved amplification and positioning of light beams, the researchers’ technique for producing quantum images may someday be useful for storing patterns of data in quantum computers and transmitting large amounts of highly secure encrypted information.
