Starting from syst em level\, it will detail the design considerations for non-multiplexed\, semi-autonomous\, transmon qubit state controllers (QSC) implemented in 14 nm CMOS FinFET technology. The QSC includes an augmented general-purpose digital processor that supports waveform generation and phase rotation ope rations combined with a low power current-mode single sideband upconversio n I/Q mixer-based RF arbitrary waveform generator (AWG). Implemented in 14 nm CMOS FinFET technology\, the QSC generates control signals in its targe t 4.5 GHz to 5.5 GHz frequency range\, achieving an SFDR > 50 dB for a sig nal bandwidth of 500 MHz. With the controller operating in the 4K stage of a cryostat and connected to a transmon qubit in the cryostat’s millikel vin stage\, measured transmon T1 and T2 coherence times were 75.5 μS and 73 μS\, respectively\, in each case comparable to results achieved using conventional room temperature controls. In further tests with transmons\, a qubit-limited error rate of 7.76x10-4 per Clifford gate is achieved\, ag ain comparable to results achieved using room temperature controls. The QS C’s maximum RF output power is -18 dBm\, and power dissipation per qubit under active control is 23 mW. An improved\, low-power design version tha t achieves half of this power will also be presented\, including some cloc king solutions for large arrays.\n\nBio:\nSudipto Chakraborty (B.
