Physicists Hack the Uncertainty Principle to See an Ion Wiggle

As the ion bounces around the chip, they reduce the uncertainty in the ion’s position by periodically hitting it with an electric field. These electric fields, if real, would push a magnesium ion ever so slightly, so their chip could be further developed to sense these dark matter particles.
