Article Synopsis
- Large-scale superconducting quantum processors face challenges due to the complex microscopic features in solid-state devices, primarily using aluminium oxide (AlO) tunnel Josephson junctions for nonlinearity in quantum operations.
- Traditional analyses often rely on an ideal sinusoidal current-phase relation, which only applies in very low-transparency conditions, but new findings reveal this doesn’t accurately represent the energy spectra of transmon artificial atoms.
- A mesoscopic model shows significant contributions from higher Josephson harmonics, improving predictions of energy spectra and suggesting that engineered harmonics could minimize charge-related errors in transmon qubits, enhancing their performance for quantum technologies.
In the rising advent of organic Li-ion positive electrode materials with increased energy content, chemistries with high redox potential and intrinsic oxidation stability remain a challenge. Here, we report the solid-phase reversible electrochemistry of the oximate organic redox functionality. The disclosed oximate chemistries, including cyclic, acyclic, aliphatic, and tetra-functional stereotypes, uncover the complex interplay between the molecular structure and the electroactivity.

However, the design and synthesis of high voltage alkali-cation reservoir anionic CPs remains challenging, hindering their practical applications. Herein, we report a family of electrically conducting alkali-cation reservoir CPs with the general formula of A-TM-PTtSA (wherein A = Li, Na, or K; TM = Fe, Co, or Mn; and PTtSA = benzene-1,2,4,5-tetra-methylsulfonamide).

Condensation events in nanometer-sized confinements are particularly interesting for the investigation of intermolecular and molecule-surface interactions. They may be accompanied by conformational adjustments representing induced fit packing patterns.
