Superconducting transmons, which are promising qubit candidates for scaled quantum computing systems, typically require individually tailored RF pulses in the 4to-6 GHz range to manipulate their states, so scaling to 106 qubits presents an enormous challenge. Providing a control line for every qubit from room temperature (RT) to the
