Researchers Produce Quantum-Entangled Images

Researchers at the NIST and University of Maryland have conducted an experiment into quantum entanglement using a new simple, versatile, and efficient method of producing quantum images. The researchers separated a single image into two light beams that were entangled by emissions from rubidium gas, the second image rotated 180° and at a slightly different color.

The researchers then experimented with alterations and fluctuations to the properties—such as phase and intensity—of one beam and noted similar changes in the other beam, allowing the team to predict changes in pixels of one image by observing the other image.

This could be a step on the road to production of a working ansible.
