TL;DR: A multi– high-frequency electron paramagnetic resonance method is used to probe the magnetic excitations of a dimer of single-molecule magnets, and the measured spectra display well-resolved quantum transitions involving coherent superposition states of both molecules.

TL;DR: Chemistry can contribute to designing robust spin systems based, in particular, on mononuclear lanthanoid complexes, the elementary unit of future quantum computers.

TL;DR: A way of enhancing coherence in solid-state molecular spin qubits without resorting to extreme dilution is presented, based on the design of molecular structures with crystal field ground states possessing large tunnelling gaps that give rise to optimal operating points, or atomic clock transitions, at which the quantum spin dynamics become protected against dipolar decoherence.

TL;DR: A pseudotetrahedral cobalt(II) complex with a positive axial zero-field splitting parameter of D = 12.7 cm(-1), as determined by high-field EPR spectroscopy, is shown to exhibit slow magnetic relaxation under an applied dc field.

TL;DR: The combined work demonstrates the feasibility that structural distortions of a magnetic core imposed by peripheral ligands can "switch on" the properties of an SMM.
