Scientists Have Captured the Sound One Atom Makes
If an atom gets excited in a laboratory, does it make a sound? Turns out that it absolutely does, albeit it's the softest sound that scientists say is physically possible. Researchers at Columbia University and Sweden's Chalmers University of Technology say that they have, for the first time, "captured" the sound a single atom makes when it moves around—a single "phonon," as it were. It's an achievement that could eventually be used as the basic science for new quantum computing devices.
