Associate Professor Atsushi Noguchi and his colleagues have theoretically analyzed the observation and control of the motion of electrons levitated in a vacuum in an electromagnetic field using a hybrid quantum system, and have found a way to apply the levitated electrons as a new quantum bit. They found that hybrid quantum systems of levitated electrons, superconducting quantum circuits, and nuclear ions can observe and control levitated electrons at the quantum level, paving the way for the application of levitated electrons as a new quantum bit with excellent quantum error tolerance. The researchers plan to conduct demonstration experiments in the future. The paper was published in the online edition of “Physical Review Research” on September 29.
