Evidence for universal relationship between the measured 1/f permittivity noise and loss tangent created by tunneling atoms
A. N. Ramanayaka, B. Sarabi, K. D. Osborn
Noise from atomic tunneling systems (TSs) limit the performance of various resonant devices, ranging in application from astronomy detectors to quantum computing. Using devices con…
Superconducting TiN Films Sputtered over a Large Range of Substrate DC Bias
H. M. Iftekhar Jaim, J. A. Aguilar, B. Sarabi +5
We have investigated properties of superconducting titanium nitride (TiN) films that were sputtered over a large range of RF-induced DC bias voltage applied to the substrate. Films…
Landau-Zener population control and dipole measurement of a two level system bath
M. S. Khalil, S. Gladchenko, M. J. A. Stoutimore +3
Tunneling two level systems (TLS), present in dielectrics at low temperatures, have been recently studied for fundamental understanding and superconducting device development. Acco…
Evidence for hydrogen two-level systems in atomic layer deposition oxides
M. S. Khalil, M. J. A. Stoutimore, S. Gladchenko +10
Two-level system (TLS) defects in dielectrics are known to limit the performance of electronic devices. We study TLS using millikelvin microwave loss measurements of three atomic l…
A Josephson junction defect spectrometer for measuring two-level systems
M. J. A. Stoutimore, M. S. Khalil, C. J. Lobb +1
We have fabricated and measured Josephson junction defect spectrometers (JJDSs), which are frequency-tunable, nearly-harmonic oscillators that probe strongly-coupled two-level syst…
An analysis method for asymmetric resonator transmission applied to superconducting devices
M. S. Khalil, M. J. A. Stoutimore, F. C. Wellstood +1
We examine the transmission through nonideal microwave resonant circuits. The general analytical resonance line shape is derived for both inductive and capacitive coupling with mis…
