Demonstration of a Quantum Noise Limited Traveling-Wave Parametric Amplifier
Nikita Klimovich, Peter Day, Shibo Shu +3
Recent progress in quantum computing and the development of novel detector technologies for astrophysics is driving the need for high-gain, broadband, and quantum-limited amplifier…
Strong kinetic-inductance Kerr nonlinearity with titanium nitride nanowires
Chaitali Joshi, Wenyuan Chen, Henry G. LeDuc +2
Thin films of disordered superconductors such as titanium nitride (TiN) exhibit large kinetic inductance (KI), high critical temperature, and large quality factors at the single-ph…
A quantum electromechanical interface for long-lived phonons
Alkim Bozkurt, Han Zhao, Chaitali Joshi +3
Controlling long-lived mechanical oscillators in the quantum regime holds promises for quantum information processing. Here, we present an electromechanical system capable of opera…
Nonlinearity and wideband parametric amplification in an NbTiN microstrip transmission line
Shibo Shu, Nikita Klimovich, Byeong Ho Eom +4
The nonlinear response associated with the current dependence of the superconducting kinetic inductance was studied in capacitively shunted NbTiN microstrip transmission lines. It…
Improving the dynamic range of single photon counting kinetic inductance detectors
Nicholas Zobrist, Nikita Klimovich, Byeong Ho Eom +8
We develop a simple coordinate transformation which can be employed to compensate for the nonlinearity introduced by a Microwave Kinetic Inductance Detector's (MKID) homodyne reado…
Full-Array Noise Performance of Deployment-Grade SuperSpec mm-wave On-Chip Spectrometers
K. S. Karkare, P. S. Barry, C. M. Bradford +15
SuperSpec is an on-chip filter-bank spectrometer designed for wideband moderate-resolution spectroscopy at millimeter wavelengths, employing TiN kinetic inductance detectors. Super…
