| 520 | _ | _ | |a The majority of the scientific research community for quantum computing agrees that an estimated number of around 106 qubits are required to build a universal quantum computer [1]. This number leads to foreseeable connectivity bottlenecks to feed all the required biasing, control and read-out signals into and out of the cryostat. A proposed solution is local cryogenic classical electronics, bringing control and read-out closer to the quantum bits themselves.For this task, the ZEA-2 – Electronic Systems institute – develops classical electronic systems using modern CMOS technologies, due to their low area footprint, ultra-low power consumption and natural synergy with semiconductor qubits. This poster highlights the ongoing development and measurement results at ZEA-2 for integrated cryogenic circuits and co-integrating them directly with qubits. This includes experimental results of a qubit bias voltage digital-to-analog converter (Bias-DAC) in a bulk 65 nm CMOS technology [2], placed at the milli-Kelvin stage alongside the qubit [3,4]. Results of cryogenic supply regulation circuits in an advanced 22nm FDSOI CMOS process are shown as well [5]. Furthermore, a brief introduction into CMOS and possible options for an optimized cryogenic specific CMOS technology is given to enhance future IC designs in power efficiency and outlook to qubit readout. This method of integration paves a way for QC scalability.[1] Vandersypen, L.M.K., Bluhm, H., Clarke, J.S. et al.
