Quantum computing can potentially outperform today’s most powerful supercomputers to solve certain important, complex problems related to materials, medicine, energy, and climate. One of the most prominent quantum computing platforms, the superconducting qubit, operates in the microwave regime and uses conventional microwave systems for qubit control and readout. A key challenge in scaling these systems to many qubits relates to the thermal load and physical footprint associated with the cryogenic RF hardware that links control equipment at room temperature to the quantum processor. In this talk, I will touch on some of the challenges of RF hardware scalability and present some solutions being investigated.
