Predefined Quantum Wiring Packages
Integrated wiring and cold-electronics configurations optimised for the Proteox dilution refrigerator platform. Built around representative superconducting- and spin-qubit architectures, these packages provide a proven starting point based on experience from comparable installations and established experimental practice:
- Reduced risk of integration issues, simplified procurement, and a shorter path from installation to first measurements.
- Integrated into Proteox secondary inserts, allowing the complete signal-chain assembly to be installed, serviced, upgraded, or exchanged without disturbing the rest of the refrigerator.
- Each package is tested for thermal and electrical performance and can be adapted to suit specific QPU requirements.
Superconducting Qubit Configuration
Designed around a representative nine-qubit flux-tuneable transmon architecture with three multiplexed readout channels. It provides 39 microwave and RF coaxial lines, divided according to their function within the quantum processor:
- 21 Z and tuneable-coupler flux lines
- 9 XY control lines for microwave qubit control
- 3 TWPA pump lines
- 3 Readout TX lines
- 3 Readout RX lines with HEMT amplifier
Spin Qubit Configuration
Designed around a representative six-qubit gate-defined silicon spin architecture with filtered DC biasing, broadband baseband control, microwave ESR control, and RF reflectometry readout:
- 24 filtered twisted-pair DC lines for static gate biasing and low-frequency control
- 12 baseband lines for fast gate pulses, exchange control, and detuning
- 1 ESR line for microwave spin control
- 1 Readout TX and 1 Readout RX line for reflectometry-based spin readout
- Directional coupler, DC block, and cryogenic SiGe HBT amplifier
