Using optimal control theory different ways for the transfer of electron spin polarization onto nuclear spins have been investigated in electron-nuclear spin systems. This method is used for signal enhancement in magnetic resonance experiments. The analyzed 2 - and 3-spin systems with realistic relaxation parameters provide detailed insight into the processes involved here.
Experimentally quantum gates have been implemented by NMR spectroscopy, under the conditions of an electron-nuclear spin system and this has been verified through a process tomography. Furthermore the controllability of a fivefold labelled heteronuclear spin system has been demonstrated by the production of pseudo-pure states. In addition a quantum algorithm for computing the Jones polynomial, a knot invariant, has been implemented.
