• total spin, leading to slow magnetic relaxation and magnetic hysteresis at low temperatures. Combined with their long coherence times they could open the door to quantum computing [5][6]. After the first SMM was discovered in 1980 [7][8], for the next 15 years the SMM field was dominated by cluster

The design of a suitable system that includes quantum bits (qubits) and quantum gates (qugates) is the main challenge to realize quantum computing. There, the electronic spins of

• magnetically anisotropic lanthanide ions can possibly act as basic units of quantum computing, i.e., as qubits. Universal qugates may be engineered by designing one molecule with two interacting lanthanide ions [17]. We are particularly interested in generating dinuclear lanthanide complexes with a bridging

The possible gate and measurement rates estimated in relation to the decoherence processes for these qubits are within the reach of the threshold for fault-tolerant quantum computing

Quantum computing, the manipulation of data encoded in qubits instead of bits of information such as spin states of electrons or of an atomic nucleus, has been a
