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.

The slides and their accompanying material from the workshop, listed according to the topic in the order they were presented:
