Abstract

We consider semiconductor double dot system with single electron localized in it as quantum bit (qubit) candidate for quantum computing purposes. The interaction of qubit with environment (phonon bath) and detector (quantum point contact) lead to modification of electron dynamics. Phonon induced decoherence rates are obtained. Detector current noise spectrum is derived.
