Abstract: A cryogenic cooling system for use in quantum computing applications can include a plurality of cryogenic cooling stages. Each of the plurality of cryogenic cooling stages can include a plurality of interleaved cooling units. The plurality of interleaved cooling units can include a first cooling unit and a second cooling unit. Each of the plurality of interleaved cooling units can have an associated operating temperature range. One or more signal lines that couple one or more classical processors to one or more quantum systems can pass through each of the plurality of interleaved cooling units for each of the plurality of cryogenic cooling stages.

Abstract: This disclosure is directed to a quantum computing system (QCS) that includes a cryogenic sub-system, a signal-generating element, a first signal-splitting element, a first transmission path, a second transmission path, a third transmission path, and a quantum device. A first environment is located outside the cryogenic sub-system and a second environment is associated with the cryogenic sub-system. The signal-generating element generates a first signal. The first signal-splitting element is positioned within the second environment. The quantum device is positioned within the cryogenic sub-system. The first transmission path transmits the first signal from the signal-generating element to the first signal-splitting element. The first signal-splitting element subdivides the first signal into a second signal and a third signal. The third transmission transmits the third signal from the first signal-splitting element to the first environment. The second transmission path transmits the second signal from the first signal-splitting element to the quantum device.
