In Situ Interferometric Spatial Mapping Of A Microwave Kinetic Inductance Detector Array
Chris Albert, Ritoban Basu Thakur, Farzad Faramarzi +7
We present a method of spatially mapping microwave kinetic inductance detector (MKID) arrays, in a dark setup. MKIDs are superconducting natively multiplexed resonators which enabl…
Magnetic-Field and Temperature Limits of a Kinetic-Inductance Traveling-Wave Parametric Amplifier
Lucas M. Janssen, Farzad Faramarzi, Henry G. LeDuc +5
Kinetic-inductance traveling-wave parametric amplifiers (KI-TWPAs) offer broadband near-quantum-limited amplification with high saturation power. Due to the high critical magnetic…
A Near Quantum Limited Sub-GHz TiN Kinetic Inductance Traveling Wave Parametric Amplifier Operating in a Frequency Translating Mode
Farzad Faramarzi, Sasha Sypkens, Ryan Stephenson +4
We present the design and experimental characterization of a kinetic-inductance traveling-wave parametric amplifier (KI-TWPA) for sub-GHz frequencies. KI-TWPAs amplify signals thro…
Kinetic Inductance and nonlinearity of MgB2 Films at 4K
J. Greenfield, C. Bell, F. Faramarzi +6
We report on the fabrication and characterization of superconducting magnesium diboride (MgB) thin films intended for quantum-limited devices based non-linear kinetic inductanc…
A 4-8 GHz Kinetic Inductance Travelling-Wave Parametric Amplifier Using Four-Wave Mixing with Near Quantum-Limit Noise Performance
Farzad Faramarzi, Ryan Stephenson, Sasha Sypkens +3
Kinetic inductance traveling-wave parametric amplifiers (KI-TWPA) have a wide instantaneous bandwidth with near quantum-limited performance and a relatively high dynamic range. Bec…
