Electrons have been trapped for the first time in a Paul trap. This opens the path to controlling trapped electron qubits much in the same way as trapped ions with the main differences that no laser light is required and that electrons are much lighter. Thus a trapped electron quantum computer could operate with less technical overhead and faster that a trapped ion system.
