  We introduce a novel superconducting qubit architecture utilizing parallel
arrays of Josephson junctions. This design offers a substantialy improved
relative anharmonicity, typically within the range of $|\alpha_r| \approx 0.1 -
0.3$, while maintaining transition matrix elements in both the charge and flux
channels that are on par with those of transmon qubits. Our proposed device
also features exceptional tunability and includes a parameter regime akin to an
enhanced version of the fluxonium qubit. Notably, it enables an additional
order of magnitude reduction in matrix elements influenced by flux noise, thus
further enhancing its suitability for quantum information processing
applications.
