Third harmonic-mediated amplification in TWPA
E. Rizvanov, S. Kern, P. Neilinger +1
In Josephson Traveling-Wave Parametric Amplifiers, higher-order harmonics of the pump tone and its sidebands are commonly present and typically regarded as parasitic. Consequently,…
Optical and transport properties of NbN thin films revisited
Samuel Kern, Pavol Neilinger, Magdaléna Poláčková +4
Highly disordered NbN thin films exhibit promising superconducting and optical properties. Despite extensive study, discrepancies in its basic electronic properties persist. Analys…
Design of deeply cooled ultra-low dissipation amplifier and measuring cell for quantum measurements with a microwave single-photon counter
O. G. Turutanov, A. M. Korolev, V. I. Shnyrkov +6
The requirements and details of designing a measuring cell and low-back-action deeply-cooled amplifier for quantum measurements at 10 mK are discussed. This equipment is a part of…
Reflection-enhanced gain in traveling-wave parametric amplifiers
S. Kern, P. Neilinger, E. Iľichev +12
The operating principle of traveling-wave parametric amplifiers is typically understood in terms of the standard coupled mode theory, which describes the evolution of forward propa…
A numerical extrapolation method for complex conductivity of disordered metals
S. Kern, P. Neilinger, D. Manca +3
Recently, quantum corrections to optical conductivity of disordered metals up to the UV region were observed. Although this increase of conductivity with frequency, also called ant…
