  1. 1. Towards measuring quantum sound

    Author : Maria Ekström; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surface acoustic wave; interdigital transducer; artificial atom; qubit; superconducting circuits; cryogenic temperature; phonon; gigahertz frequency; quantum acoustics; unidirectional transducer;

    Abstract : One of the most fundamental phenomena occurring in nature is the interaction between single atoms and electromagnetic fields. This is studied in quantum optics to probe the quantum nature of the system. In appended Paper I, we demonstrated that an artificial atom can couple to propagating sound, which is the acoustic analogue of quantum optics. READ MORE

    Abstract : Surface acoustic waves (SAWs) are mechanical vibrations that propagate on the surface of solids while dissipating little power, consequently enabling them to propagate freely over long distances. The speed and wavelength of SAWs are reduced a five order of magnitude compared to when light is used as a carrier at gigahertz frequencies. READ MORE
