To exploit a given physical system for quantum information processing, it is critical to understand the different types of noise affecting quantum control. Distinguishing coherent and incoherent errors is extremely useful as they can be reduced in different ways. Coherent errors are generally easier to reduce at the hardware level, e.

- Advanced sodium-oxygen (Na-O2) batteries are promising for large-scale energy storage because they use inexpensive materials and have better performance than lithium-oxygen batteries, but the exact transport mechanism of superoxide ions remains unclear.
- Using ESR spectroscopy, researchers identified and quantified hydroperoxyl (HO2) radicals in Na-O2 cells, providing direct evidence of these species and their role in superoxide transport that facilitates the formation of sodium superoxide (NaO2) during battery cycling.
- The study also connects superoxide levels in the electrolyte to crystal growth of NaO2, while revealing that certain radicals formed from HO2 interaction with the solvent may lead to electrolyte degradation. *
