      abstract     = {For running advanced algorithms on a universal quantum
                      computer, millions of qubits are required. To make use of
                      quantum effects, state-of-the-art solid-state qubit devices
                      have to be cooled to mK temperatures, which limits the
                      systems’ scalability with room temperature (RT)
                      electronics. We present the direct co-integration of a
                      scalable, fully integrated, eight channel Bias-DAC designed
                      in a 65-nm bulk CMOS technology and a Si/SiGe spin qubit
                      device at the mixing chamber (MC) of a dilution refrigerator
                      operating below 45 mK MC temperature. As a full proof of
                      principle, the bias of a single electron transistor used as
                      a sensing dot, as well as a single and double quantum dot
                      bias of the qubit device is reported. The slow drift of the
                      DAC $S\&H$ output circuit of 0.96 μV/s leads to a
                      calculated prospective power consumption of 64.5 pW/ch for
                      DC qubit bias voltages generated at low temperature.},
