Demonstration of a scalable all-solid-state refrigerator exploiting diffusion geometries and limiting interfacial conductances at temperatures below 1 kelvin
Robert M. Young, Zachary Stegen, John X. Przybysz +32
Solid-state refrigerators using Normal-metal/Insulator/Superconductor (NIS) junctions have previously demonstrated excellent electron cooling but limited ability to cool phonons. T…
Programmable CMOS DAC Operating in Cryogenic Environments for Controlling Superconducting Qubits
A. Pelteku, D. Reitz, M. Covington +15
This paper presents the design and test results of a CMOS current-based Digital to Analog Converter (DAC) that operates at cryogenic temperatures and that can be used to precisely…
Fast Microwave-free State Preparation and Measurement of Superconducting Qubits
R. Abraham, F. Amet, P. Anderson +212
Fast, high-fidelity, scalable state preparation and measurement is critical to the realization of a quantum computing system. The state-of-the-art methods for preparation and reado…
Transmon Phase Gates Controlled by Superconducting Soliton DAC
Derek Reitz, Tony X. Zhou, Aditya Sharma +10
We introduce a superconducting digital-to-analog converter (DAC) that filters control noise, provides native multiplexing, performs quantum gates in nanoseconds, and can be control…
Fast, Lifetime-Preserving Readout for High-Coherence Quantum Annealers
Jeffrey A. Grover, James I. Basham, Alexander Marakov +15
We demonstrate, for the first time, that a quantum flux parametron (QFP) is capable of acting as both isolator and amplifier in the readout circuit of a capacitively shunted flux q…
Scale-invariant magnetoresistance in a cuprate superconductor
P. Giraldo-Gallo, J. A. Galvis, Z. Stegen +14
The anomalous metallic state in high-temperature superconducting cuprates is masked by the onset of superconductivity near a quantum critical point. Use of high magnetic fields to…
Evolution of superconducting correlations within magnetic-field-decoupled CuO(2) layers of La(1.905)Ba(0.095)CuO(4)
Z. Stegen, Su Jung Han, Jie Wu +7
We explore the evolution of superconductivity in La(2-x)Ba(x)CuO(4) with x=0.095 in magnetic fields of up to 35 T applied perpendicular to the CuO(2) planes. Previous work on this…
Doping-Driven Collapse of the SDW Correlation Gap in SmFeAsOF
Scott C. Riggs, R. D. McDonald, J. B. Kemper +8
We report the Hall resistivity, of polycrystalline SmFeAsOF for four different fluorine concentrations from the onset of superconductivity through the collap…
Log-T divergence and Insulator-to-Metal Crossover in the normal state resistivity of fluorine doped SmFeAsO1-xFx
S. C. Riggs, J. B. Kemper, Y. Jo +8
We report the resistivity of a series of fluorine-doped SmFeAsO1-xFx polycrystalline superconductors in magnetic fields up to 60T. For underdoped samples (x < 0.15), the low temper…
