Google Builds Circuit to Solve One of Quantum Computing’s Biggest Problems
One of the big limiters to today’s quantum computing systems is that while their superconducting qubits live in a cryogenic enclosure at less than 1 kelvin, all the control and readout circuits must be at room temperature. For today’s sub-100-qubit systems, there’s enough space for specialized RF cabling to come in and out of the enclosure. But to scale up to the million-qubit systems needed to do really cool stuff, there just won’t be enough room.
