Collectively Enhanced Interactions in Solid-state Spin Qubits — •Hendrik Weimer — Institut für Theoretische Physik, Leibniz Universität Hannover

I will show how to engineer collective enhancement of dipolar interactions in random spin networks. While disordered interactions typically lead to localization of all eigenstates, the presence of a transverse magnetic field can result in the appearance of a single delocalized mode suitable for the mediation of long-range quantum logic between remote spin registers [1]. I will discuss a specific implementation based on nitrogen-vacancy defects in diamond.
