For these purposes Qblox has developed a highly distributed control architecture where modules execute control and readout operations on a small number of qubits by incorporating processors capable of sequencing pulses, their parameters, and measurement operations in real time. Upon executing qubit measurements, these modules transfer their results into an extended star network that allows for the distribution of these results fast and scalable. We here demonstrate fast feedback protocols between 120 control nodes, for instance capable of controlling and reading out 30 superconducting qubits.
