• Abstract: This paper investigates the implementation of microwave and mm-wave integrated circuits for control and readout of electron/hole spin qubits, as elementary building blocks for future emerging quantum computing technologies. In particular, it summarizes the most relevant readout and control techniques of electron/hole spin qubits, addresses the feasibility and reports some preliminary simulation results of two blocks: transimpedance amplifier (TIA) and pulse generator (PG). The TIA exhibits a transimpedance gain of 108.5 dB Ohm over a -3dB bandwidth of 18 GHz, with input-referred noise current spectral density of 0.89 pA/root(Hz) at 10 GHz. The PG provides a mm-wave sinusoidal pulse with a minimum duration time of 20 ps.
