The Microdrum Used in This Study (IMAGE) Ecole Polytechnique Fédérale de Lausanne Caption Photograph of the chip used in the experiment to couple a microwave cavity to a micrometer-size drum (the sharp purple pencil tip is placed as a scale). Inset shows a scanning electron micrograph of the drum. The top membrane of the drum is suspended only 50nm (1/2000th of the diameter of hair) above a metal plate. This is then used to manipulate and amplify microwaves in the quantum regime. Credit N. R. Bernier and L. D. Tóth (EPFL). Usage Restrictions For media purposes only. Please mention credit.
