Cryogenic control electronics
Electronics that operate at cryogenic temperatures next to the qubits and generate control signals and read out results, replacing one line from room temperature per qubit.
Scope
In scope: cryo-CMOS, superconducting digital logic and photonic links used to control and read out qubits in the cryostat. Out of scope: the qubits (quantum/fault-tolerant-quantum-computer) and the decoder algorithm (quantum/real-time-qec-decoder).

Required by
- Fault-tolerant quantum computer One coaxial line per qubit does not scale to a million qubits; control and readout electronics must sit in the cold.
- Real-time quantum error-correction decoder The decoder reads syndromes from the control system, and placing it near the qubits shortens the path and the latency.
