MCM Integration

3D Integration & Packaging

Dense, low-latency interconnect between SFQ controllers and superconducting qubit arrays.

Superconducting digital control chip closer to the qubits

CRYOGENIC INTEGRATION

Enabling digital control closer to the qubits.

Through MCM bonding engineered for deep-cryogenic environments, low-power superconducting digital control units are co-located with qubits in the same cryogenic stage, dramatically reducing control and readout signal fan-out while shortening signal paths and minimizing latency.
