A spin qubit flipping states also flips the field acting on nearby nuclear spins between two orientations (shown as arrows). The nuclear spin vector follows a path conditional on the specific trajectory of the qubit, so that they are entangled.

This schedule is a rough guide - we will however try to stick to it but the emphasis will be on the discussion. The meeting is intended to be informal.

Examples of magnetic molecules. Top: Fe8. Eight s=5/2 FeIII ions are forming a total spin S=10 (six spins are parallel and antiparallel to the other two); middle: Ni12 with a total spin S=12; bottom: Mn12 with a total spin S=10.
