      abstract     = {Universal quantum computing, requires a scalable system
                      with millions of qubits. One of the current bottlenecks is a
                      fast and high fidelity readout without limiting the
                      scalability by area consumption, wiring, or power
                      dissipation. We address this challenge by developing an
                      integrated readout circuitry (IC), in a 22 nm FD-SOI
                      technology, operating at deep cryogenic temperatures. The IC
                      will be connected to a Single Electron Transistor (SET). The
                      prototype is made for reading out two SETs. It implements a
                      high speed mode, to perform a single bit readout to distinct
                      │0〉and │1〉state and a high resolution mode for
                      tuning, which amplifies the signal and passes it to the
                      room-temperature electronics.We characterize this IC inside
                      a closed cycle Gifford-McMahon cryostat at a temperature of
                      6 K. The measurement shows a power consumption of 33.6
                      µW/SET for the single bit readout and 216 µW for the
                      high-resolution mode. With a sampling time of 2×1 µs, the
                      circuit shows low noise of 223 pA (1σ) for single bit
                      readout, while the high-resolution mode has an
                      input-referred noise level of 188 pA RMS (10 Hz to 1
                      MHz).With its high bandwidth, low input noise and low power
                      consumption, this IC paves the way for scalable integrated
                      readout and is a decisive step on the way to universal
                      quantum computing},
