Although the architecture of a quantum computer depends on the implemented qubit system, I still wonder what the general structure of hardware parts would be. Evidently, a quantum computer isn't merely comprised of qubits, so probably multiple devices must be required to realize the existence of a physical quantum computer. Which devices would that be and what is the pertaining purpose of each component. In case certain helpful sources are available for finding such data, I would gladly like to receive a reference then. A schematic or primitive blueprint would also be highly appreciated. Thank you in advance.
