Experimental physicists led by Gerhard Kirchmair, together with theoretical physicists at the University of Oulu, Finland, have succeeded for the first time in controlling protected quantum states—so-called dark states—in superconducting quantum bits. The entangled states are 500 times more robust and could be used in quantum simulations. The method could also be used on other technological platforms.
