Q:Nothing new? The entire field of quantum mechanics is considered brand spanking new compared to other disciplines. Einstein was the man that dubbed this phenomenon 'spooky action at a distance' because he himself was not familiar with the mechanics behind it, of course. Einstein must have thought nature was mighty spooky; we all know how he ended up being a nobody and all.
Yep, Einstein (and Schrödinger and some others) didn’t accept Quantum Mechanics at the time, and even they reneged on their (crucial) role in its development. I’m sure they would not think the same thing today (the empirical evidence is overwhelming, this experiment is only one more). Look here, for example.
[Oh, and from the very own post: “There is not new physics here, though, but a neat demonstration of physics.”]
"Spooky" Quantum Entanglement Reveals Invisible Objects (via National Geographics).
In the new experiment, the physicists entangled photons in two separate laser beams with different wavelengths, and hence color: one yellow and one red.[…] The team passed the red light beam through etched stencils and into cutouts of tiny cats and a trident, about 0.12 inches (3 millimeters) tall. The yellow beam traveled on a separate line, never hitting the objects. What’s more, the etched shapes were designed to be invisible to yellow light. […] After the red light passed by the objects, the physicists ran it together with the yellow laser beam at both parallel and right angles. The red light was then discarded, and the yellow light headed for a camera. There, that yellow light revealed a picture of the object. And a negative of the picture emerged from the light that had interfered at a right angle.
"The phenomena really arises from the interference of the photons together,” Lemos says. “It’s not that the red photons have changed the yellow ones, it’s that quantum mechanics says they have to share [wavelength] phases which we can detect to see a picture.”
Nothing spooky (unless you consider nature is spooky), and nothing new because quantum entanglement is known (and accepted) from 1935 or so. But an interesting experiment anyway, of course.
Drums to start the week. These people of Animusic do some fancy genuine stuff.
