  7. 40. Three-wave mixing in Josephson travelling-wave parametric amplifiers

    Författare :Hampus Renberg Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three-wave mixing; lumped-element; four-wave mixing; SNAIL; Josephson junction; travelling-wave parametric amplifier; parametric amplifier; parametric amplification; resonant phase matching.; rf-SQUID;

    Sammanfattning : This work explores possibilities of building a wide-band, quantum-limited low-noise amplifier by means of three-wave mixing (3WM) in different kinds of Josephson travelling-wave parametric amplifiers (TWPAs). We extend the theory of the continuous three-mode model to include any number of up-converted modes in the small frequency limit where the frequency dispersion is close to linear. LÄS MER
