Abstract
Technological challenges for quantum information technologies lead us to consider aspects of molecular magnetism in a radically new perspective. The design of new derivatives and recent experimental results on molecular nanomagnets are covered in this tutorial review through the keyhole of basic concepts of quantum information, such as the control of decoherence and entanglement at the (supra-)molecular level.

Summary
Reasons: the lithographic steps will become extremely demanding and expensive; processing and communication of information at the nanometre scale will be hard to maintain efficient in terms of energy dissipation and speed, just to mention a few technological issues, but more fundamental ones will rise. Filippo Troiani tion of quantum information processing in semiconductor nanostructures and molecular nanomagnets His interest is focused on different approaches for the coherent manipulation of molecular spin-clusters, and on the phenomena of quantum entanglement and decoherence in these systems. Marco Affronte novel results by studying thermodynamic properties of several molecular magnetic systems and superconductors and this led him to propose molecular antiferromagnetic rings as suitable candidates for quantum computation He works as an expert in different panels for Information and Communication. Molecular nanomagnets are real examples of finite spin chains (1D) or clusters (0D), and they constitute a new benchmark for testing models of interacting quantum objects In this tutorial review, we discuss possible uses of molecular spin clusters for quantum-information processing presenting, firstly, some basic concepts (qubits, quantum gates, entanglement, decoherence); we make examples based on specific molecular spin systems. We take the liberty to present some new ideas which are, at the moment, at an embryonic stage but look very promising
