Schrödinger’s cat is back.
For the first time ever,a picture was made by using the quantum entanglement effect. The images above were generated by using a cat-stencil and entangled photons. But there’s much more than that: The photons who made up the “pic” have never had contact with the actual stencil. Also,the photons that illuminated the stencil were not seen by the camera at all.
Gabriela Barreto Lemos from the Austrian Academy of Sciences in Vienna made ghostly pics by creating yellow and red pairs of entangled photons; the yellow ones were fired at the stencil, the red ones were sent to the camera.
