Noise factor of Brillouin amplifiers
John H. Dallyn, Nils T. Otterstrom, Matt Eichenfield +2
Stimulated Brillouin scattering (SBS), an optical nonlinearity arising from photon-phonon interactions, has formed the basis for a large class of optical signal processing devices,…
Noise and dynamics in acoustoelectric waveguides
Ryan O. Behunin, Andrew Shepherd, Ruoyu Yuan +5
We present a quantum field theoretic formulation of acoustoelectric interactions in waveguide-like systems of arbitrary cross-section. Building on an open quantum systems approach,…
Phonon decoherence produced by two-level tunneling states
Ryan O. Behunin, Taylor Ray, Dylan Chapman +3
Phonon modes within pristine crystalline resonators now routinely reach the quantum ground state. Such systems are attractive for quantum information science applications, as advan…
Lifetime-limited Gigahertz-frequency Mechanical Oscillators with Millisecond Coherence Times
Yizhi Luo, Hilel Hagai Diamandi, Hanshi Li +9
High-frequency mechanical oscillators with long coherence times are essential to realizing a variety of high-fidelity quantum sensors, transducers, and memories. However, the unpre…
