    "abstract": "We present an open loop (bang-bang) scheme to control decoherence in a\ngeneric one-qubit quantum gate and implement it in a realistic simulation. The\nsystem is consistently described within the spin-boson model, with interactions\naccounting for both adiabatic and thermal decoherence. The external control is\nincluded from the beginning in the Hamiltonian as an independent interaction\nterm. After tracing out the environment modes, reduced equations are obtained\nfor the two-level system in which the effects of both decoherence and external\ncontrol appear explicitly. The controls are determined exactly from the\ncondition to eliminate decoherence, i.e. to restore unitarity. Numerical\nsimulations show excellent performance and robustness of the proposed control\nscheme.",
