Photothermal resistivity alignment of optical fibers to SNSPD
Martin Baránek, Dušan Lorenc, Tomáš Ščepka +5
We demonstrate a straightforward optoelectronic fiber alignment technique for superconducting nanowire single-photon detectors (SNSPDs) that exploits the temperature-dependent resi…
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,…
Josephson Traveling Wave Parametric Amplifiers with Plasma oscillation phase-matching
Emil Rizvanov, Samuel Kern, Pavol Neilinger +1
High gain and large bandwidth of traveling-wave parametric amplifier exploiting the nonlinearity of Josephson Junctions can be achieved by fulfilling the so-called phase-matching c…
Numerical modeling of SNSPD absorption utilizing optical conductivity with quantum corrections
Martin Baránek, Pavol Neilinger, Samuel Kern +1
Superconducting nanowire single-photon detectors are widely used in various fields of physics and technology, due to their high efficiency and timing precision. Although, in princi…
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…
