    "abstract": "A central challenge for implementing quantum computing in the solid state is\ndecoupling the qubits from the intrinsic noise of the material. We investigate\nthe implementation of quantum gates for a paradigmatic, non-Markovian model: A\nsingle qubit coupled to a two-level system that is exposed to a heat bath. We\nsystematically search for optimal pulses using a generalization of the novel\nopen systems Gradient Ascent Pulse Engineering (GRAPE) algorithm. We show and\nexplain that next to the known optimal bias point of this model, there are\noptimal shapes which refocus unwanted terms in the Hamiltonian. We study the\nlimitations of controls set by the decoherence properties. This can lead to a\nsignificant improvement of quantum operations in hostile environments.",
