Researchers from NIST and the University of Colorado have successfully developed a method to trap and control phonons, which are sound particles similar to photons in light. This breakthrough has significant implications for future applications in quantum computing. The findings were published in Physical Review X, with an initial draft available on ArXiv. The ability to manipulate phonons could lead to advancements in information processing and communication technologies. This research represents a notable step forward in the field of quantum mechanics.

Hi everyone! I honestly wasn't sure where I should put this, but I had recently come across this online article from Scientific American about researchers from NIST and the University of Colorado having developed the ability to trap and gain control of "phonons" (sound "particles", roughly analogous with photons for light), and the possible future applications in areas like quantum computing.

Here is the link from Scientific American:

The article states that the researchers published in Physical Review X, but I believe this ArXiv post contains the initial draft of the paper in question:

I built a device designed to brake angular velocity which seems to work based on below, i used a flexible shaft that could bow up and down so i could visually see what was happening for the prototypes. If you spin two wheels in opposite directions each with a magnitude of angular momentum L on a rigid shaft (equal magnitude opposite directions), then rotate the shaft at 90 degrees to the momentum vectors at constant angular velocity omega, then the resulting torques oppose each other...
