The quantum device engineering cycle consists of several steps. A target application influences the chip design, in which an equivalent circuit and its target parameters are determined. This design serves as the input for a second design step in which the circuit design and geometry of the device is determined, taking into account constraints of the fabrication process. After fabricating the device, the system is characterized, resulting in knowledge about the system. This knowledge is then used to iterate on the design steps. Figure from [55]
