A three-wave mixing kinetic inductance traveling-wave amplifier with near-quantum-limited noise performance
M. Malnou, M. R. Vissers, J. D. Wheeler +4
We present a theoretical model and experimental characterization of a microwave kinetic inductance traveling-wave amplifier (KIT), whose noise performance, measured by a shot-noise…
Measuring a topological transition in an artificial spin 1/2 system
M. D. Schroer, M. H. Kolodrubetz, W. F. Kindel +6
We present measurements of a topological property, the Chern number (), of a closed manifold in the space of two-level system Hamiltonians, where the two-level system…
Improved superconducting qubit coherence using titanium nitride
J. Chang, M. R. Vissers, A. D. Corcoles +9
We demonstrate enhanced relaxation and dephasing times of transmon qubits, up to ~ 60 μs by fabricating the interdigitated shunting capacitors using titanium nitride (TiN). Compare…
