Abstract
A novel and useful fully integrated quantum computer containing both quantum core circuitry and associated classical electronic control circuits on the same monolithic die. The integrated quantum computer avoids ESD loading on the quantum structures and minimizes the need for long interconnects with resultant large parasitic inductances and capacitances. Such parasitics reduce the maximum operating frequency of the realized quantum core structures. A cryostat unit functions to provide several temperatures to the quantum computer including a temperature to cool the quantum core to approximately 4° K and the interface SoC to 77° K. Alternatively, the interface circuitry is also integrated with the main QPU on the same die. A programmable pattern generator executes sequences of instructions that control the quantum core. In accordance with the sequences, a pulse generator functions to generate the control signals that are input to the quantum core to perform quantum operations.
