      abstract     = {A universal quantum computer requires the control and read
                      out of millions of physical quantum bits (qubits). Due to
                      wiring limitation in current state-of-the-art dilution
                      refrigerators scaling up to millions of qubits with
                      room-temperature electronics is challenging. Integrated
                      Circuits (ICs) operating next to the qubits will help
                      solving this scalability problem but require novel
                      approaches for cryogenic circuits. This talk will focus on
                      the physical design layer of the integration of a
                      custom-designed 65nm CMOS low-power digital to analog
                      converter(DAC) for qubit bias together with a spin qubit
                      sample. In total, eight DAC channels are integrated at the
                      mixing chamber stage of a dilution refrigerator and are
                      operated at milli-kelvin temperatures. Additionally,
                      engineering aspects regarding the sample space setup,
                      cryostat wiring, and the tight density are pointed out.},
