“…It was previously demonstrated that the rotation of the ligand L 1 depends on the size of the lanthanide ion. [43] The isomer observed in 5 and 6 is in agreement with the monoclinic phase observed for the Y III and Dy III analogues. The C=C central bond length of the TTF core of 1.332(14) Å [1.312 (19) Å] again attests to the neutrality of L 1 .…”

“…The UV/Vis absorption properties of L 1 and its Y III (tta) 3 complex [43] were studied in CH 2 Cl 2 solutions (Figure 7a and c). The rationalization of the spectra through time-dependent DFT (TD-DFT) calculations was performed through a computational strategy that has already been used successfully for TTF-based systems (see Computational Details; Figure 7b and d).…”

“…[41] The utilization of 164 Dy(III) (I = 0) led to the observation of enlarged hysteresis loops at zero field, in comparison to SMMs obtained from the naturally occurring isotopic mixture. Concerning the first point, although 159 Tb-based SMMs seem promising candidates as nuclear spin qubits, the non-Kramers character of the Tb(III) ion has led to a very limited number of examples of Tb(III)-based SMMs with satisfyingly strong magnetic anisotropy.…”

One of the most ambitious technological goals is the development of devices working under the laws of quantum mechanics. Among others, an important challenge to be resolved on the way to such breakthrough technology concerns the scalability of the available Hilbert space. Recently, proof‐of‐principle experiments were reported, in which the implementation of quantum algorithms (the Grover's search algorithm, iSWAP‐gate, etc.) in a single‐molecule nuclear spin qudit (with d = 4) known as 159TbPc2 was described, where the nuclear spins of lanthanides are used as a quantum register to execute simple quantum algorithms. In this progress report, the goal of linear and exponential up‐scalability of the available Hilbert space expressed by the qudit‐dimension “d” is addressed by synthesizing lanthanide metal complexes as quantum computing hardware. The synthesis of multinuclear large‐Hilbert‐space complexes has to be carried out under strict control of the nuclear spin degree of freedom leading to isotopologues, whereby electronic coupling between several nuclear spin units will exponentially extend the Hilbert space available for quantum information processing. Thus, improved multilevel spin qudits can be achieved that exhibit an exponentially scalable Hilbert space to enable high‐performance quantum computing and information storage.

Single-Molecule Magnets (SMMs) are finite molecular species that display slow relaxation of their magnetisation, equivalent to a magnetic memory effect. Here we give an overview of how SMM behaviour can arise from the spin properties of a giant molecular spin or unpaired electrons on a single metal centre. We outline the criteria for obtaining SMM properties, and how these have developed through theoretical insight to lead to the rapid advancement of SMM performance. We discuss the progression of the field from the original Mn12 polymetallic cluster, to carefully engineered coordination complexes of Ln ions. Classes of compounds discussed include 3d, 3d-4f and 4f polymetallic clusters, 3d and 4f monometallic complexes, and homo-and hetero-metallic exchange-coupled SMMs, including those bridged by radical ligands and/or encapsulated in endohedral fullerenes. The state-ofthe-art in SMMs is discussed, leaving the reader with an up-to-date understanding of theory and synthetic design, with references to comprehensive reviews.For readers new or returning to the area, we highlight the standard experiments used to characterise SMMs -including magnetic hysteresis, zero-field cooled/field cooled magnetic susceptibility, alternating current susceptibility and magnetisation decay measurements. We highlight the common pitfalls often encountered in the literature in measurements, data analysis and structural correlation of properties. We aim to provide a clear background for relaxation mechanisms in SMMs and the quantification of performance using energy barriers, blocking temperatures and relaxation rate. The reader is directed towards a series of proof-ofconcept publications which have spearheaded the implementation of SMMs towards future applications in high density data storage, quantum information processing and spintronics.
