Quantum systems only provide value, if their states can reliably be prepared, manipulated and read-out in a controlled environment. These requirements depend on electronics and control infrastructure. Electronic circuit design must be considered in every new quantum development since it is the bridge that turns quantum physics into a controllable, measurable, and repeatable technology. On top of the initial enablement, application specific integrated circuits (ASICs) co-integrated with photonics are the key to scalable technologies.
