Abstract:
Doping in quantum information architectures is often presented as a source of decoherence for the qubit to study. However, high doped material also present additional properties that could be used in quantum computation. Here, we show that the application of GHz photons to a doped double quantum dot allows a pair of active dopant to be selected and gate operation to be implemented with potential coherence time exceeding 200 microseconds.
