SLUG Microwave Amplifier: Theory
G. J. Ribeill, D. Hover, Y. -F. Chen +2
We describe a novel scheme for low-noise phase-insensitive linear amplification at microwave frequencies based on the Superconducting Low-inductance Undulatory Galvanometer (SLUG).…
Calculations for Magnetism in SQUIDs at Millikelvin Temperatures
S. Sendelbach, D. Hover, A. Kittel +3
Here we present details of a calculation that allows us to extract a surface density of unpaired spins from flux vs. temperature experiments performed on field-cooled dc Supercondu…
Magnetism in SQUIDs at Millikelvin Temperatures
S. Sendelbach, D. Hover, A. Kittel +3
We have characterized the temperature dependence of the flux threading dc SQUIDs cooled to millikelvin temperatures. The flux increases as 1/T as temperature is lowered; moreover,…
1/f Flux Noise in Josephson Phase Qubits
Radoslaw C. Bialczak, R. McDermott, M. Ansmann +8
We present a new method to measure 1/f noise in Josephson quantum bits (qubits) that yields low-frequency spectra below 1Hz. Comparison of noise taken at positive and negative bias…
