    "abstract": "Optimal control methods for implementing quantum modules with least amount of\nrelaxative loss are devised to give best approximations to unitary gates under\nrelaxation. The potential gain by optimal control using relaxation parameters\nagainst time-optimal control is explored and exemplified in numerical and in\nalgebraic terms: it is the method of choice to govern quantum systems within\nsubspaces of weak relaxation whenever the drift Hamiltonian would otherwise\ndrive the system through fast decaying modes. In a standard model system\ngeneralising decoherence-free subspaces to more realistic scenarios,\nopenGRAPE-derived controls realise a CNOT with fidelities beyond 95% instead of\nat most 15% for a standard Trotter expansion. As additional benefit it requires\ncontrol fields orders of magnitude lower than the bang-bang decouplings in the\nlatter.",
