TL;DR: Antiferromagnetic Cr7Ni rings can be chemically linked to each other and that the coupling between their spins can be tuned by choosing the linker, and calculations are presented that demonstrate how realistic microwave pulse sequences could be used to generate maximally entangled states in such molecules.

TL;DR: The energy spectrum and the suppression of the leakage-inducing S mixing render the Cr7Ni molecule a suitable candidate for the qubit implementation, as further substantiated by the quantum-gate simulations.

TL;DR: It is shown that through supramolecular chemistry a single simple module, molecular {Cr7Ni} rings, can be assembled into structures suitable for either the CNOT or gate by choice of linker, and these structures are characterized by electron spin resonance spectroscopy.

TL;DR: Electric-quadrupole order in NpO2 could be driven by the ordering at T0 of magnetic octupoles of Gamma(5) symmetry, splitting the Np ground state quartet and leading to a singlet ground state with zero dipole-magnetic moment.
