Cryo-CMOS Readout and Control Modules for Superconducting Quantum Computing
Operates at -269°C (4K) to perform direct readout and control for multiple qubits within the cryogenic refrigerator.
Current quantum computers rely on bulky cabinets at room temperature outside the refrigerator and hundreds of cables connected to qubit chip at mK in the refrigerator, causing signal loss and severe thermal interference and leakage. This technology moves signal processing to the cryogenic stage to eliminate massive cabling. The test of connecting this cryogenic-CMOS module to the qubit chip proves its readout fidelity can match the test results with room-temperature test instruments, overcoming the infrastructure bottleneck for scaling up to 10, 20, or more qubits. Features a wide bandwidth, from 4 to 10GHz, offering cross-platform compatibility of quantum scaling infrastructures for different superconducting qubits (eg Transmon/Fluxonium qubits).
