Hierarchical Electronic Transport in Giant Mixed-Valence {Mo154} Rings Revealed in Anhydrous Single-Molecule-Layer Networks

Abstract Polyoxometalates (POMs) are redox-active metal–oxo clusters of central interest in molecular and materials chemistry. The giant mixed-valence {Mo154} ring, built from 14 repeating subunits, is a prototypical system expected to exhibit rich electronic functionality; howev...

Cryogenic time-division-multiplexed voltage control for scalable trapped-ion quantum processors

Trapped-ion quantum computers based on the quantum charge-coupled device architecture require on the order of ten trap electrodes per qubit, making the number of vacuum feedthroughs a bottleneck at the system scale. Time-division multiplexed (TDM)-based voltage control for trap e...
