  Over the past two decades, the performance of superconducting quantum
circuits has tremendously improved. The progress of superconducting qubits
enabled a new industry branch to emerge from global technology enterprises to
quantum computing startups. Here, an overview of superconducting quantum
circuit microwave control is presented. Furthermore, we discuss one of the
persistent engineering challenges in the field, how to control the
electromagnetic environment of increasingly complex superconducting circuits
such that they are simultaneously protected and efficiently controllable.
