Anomalous Loss Reduction Below Two‐Level System Saturation in Aluminum Superconducting Resonators

Advanced Quantum Technologies, 2023
Abstract Superconducting resonators are widely used in many applications such as qubit readout for quantum computing, and kinetic inductance detectors. These resonators are susceptible to numerous loss and noise mechanisms, especially the dissipation due to two‐level systems (TLS) which become the dominant source of loss in the few ...

Correction of soil acidity in the subsurface of an oxisol with sandy loam texture under no-tillage Correção da acidez do solo em subsuperfície de um latossolo de textura franco-arenosa sob plantio direto

Revista Brasileira de Ciência do Solo, 2009
In Rio Grande do Sul State (RS), Southern Brazil, aluminum saturation in many areas under no-till system is high and base saturation low in the 0.10-0.20 m layer (subsurface), which may reduce the grain yield of annual crops.
