Physicists are engineering where uncertainty shows up in quantum systems, which has applications for detecting gravitational waves, and potentially more mainstream uses, including quantum computers, navigation, and microscopy.
Atom interferometry holds great promise for making ultra-sensitive measurements in fundamental physics.
Yesterday's write-up of my Science paper ended with a vague promise to deal some inside information about the experiment. So, here are some anecdotes that you would need to have been at Yale in 1999-2000 to pick up. We'll stick with the Q&A format for this, because why not?
A little over a year ago, I visited Mark Kasevich's labs at Stanford, and wrote up a paper proposing to use a 10-m atom interferometer to test general relativity. Now, that sounds crazy, but I saw the actual tower when I visited, so it wasn't complete nonsense.
Even if you keep your distance, a black cat in your path is bad luck if you're superstitious. Similarly, in quantum physics, particles can sense the i
