Operating quantum states in single magnetic molecules — •Wolfgang Wernsdorfer — PHI and INT, Karlsruhe Institute of Technology, Germany

The endeavour of quantum electronics is driven by one of the most ambitious technological goals of today's scientists: the realization of an operational quantum computer. We start to address this goal by the new research field of molecular quantum spintronics, which combines the concepts of spintronics, molecular electronics and quantum computing [1]. The building blocks are magnetic molecules, i.e. well-defined spin qubits. Various research groups are currently developing low-temperature scanning tunnelling microscopes to manipulate spins in single molecules, while others are working on molecular devices (such as molecular spin-transistors, spin valves and filters, and carbon-nanotubebased devices) to read and manipulate the spin state and perform basic quantum operations. We will first discuss this - still largely unexplored - field and then summarize our first results [2-7]. Finally, we will discuss the new challenges of the field and the requirements to achieve them.
