Quantum Entanglement Camera Images Object With Photons That Never Come Near It
More Quantum 'magic' to try to wrap your mind around, while others use it to make things happen.
From the Article:
"In their experiment, green laser light is twice split into entangled infrared twins, one of which is in the short-wave infrared (SWIR), the other of which is in the near infrared (NIR). One of the SWIR photons then illuminates the object being imaged. Both SWIR photons are ultimately discarded, never to be observed.
But their NIR twins are the ones in the existential cage match: If the imaged object blocks its corresponding SWIR counterpart, then the NIR counterpart gets to exist. It ultimately appears as a pixel on the quantum camera’s image. If SWIR passed through the object, its NIR twin doesn’t exist. Its absence is recorded by the camera as a dark spot.
The end-result is that NIR photons create the image, although no NIR photons illuminated the object. And SWIR photons exclusively illuminated the object, although no SWIR photons are ever detected or observed.
One application of the quantum entanglement camera, Barreto Lemos says, is that the light that illuminates an object can be completely separate from the light that forms the image in the camera."

I can't get my mind around it. That makes pseudoscientists use it to sell What the Bleep Do We Know while real scientists use it make real things happen.
