  The QICK is a standalone open source qubit controller that was first
introduced in 2022. In this follow-up work, we present recent experimental use
cases that the QICK uniquely enabled for superconducting qubit systems. These
include multiplexed signal generation and readout, mixer-free readout,
pre-distorted fast flux pulses, and phase-coherent pulses for parametric
operations, including high-fidelity parametric entangling gates. We explain in
detail how the QICK was used to enable these experiments.
