Abstract: We compare our approach of placing the electronics as close to the qubits as possible with other approaches like the cryogenic use of FPGAs or scaling of room temperature electronics [3] [4]. Especially the connectivity towards room temperature is a key aspect and will be examined in detail. Next to connectivity, other important challenges for the control electronics are area demand and power consumption. Both have been investigated and the figures of merit of different implementations will be shown. The placement of the electronics next to the qubits into the cryogenic environment shows additional advantages like improved noise behaviour. We will show how this aspect influences the choice of component architectures.For demonstration of the suitability of our approach first results for a modelled electronic system will be presented.
