Engineering Insights
1. Qubit Array Architecture
The hexagonal qubit arrangement (visible in Component ①) allows for:
- Nearest-neighbor coupling: 40MHz interaction frequency
- Frequency crowding: 100-150MHz spacing between qubits
- Coherence times: T1=85Ξs, T2=50Ξs (at 15mK)
2. Cryogenic Innovation
The cooling system (Component ②) features:
- 3-stage refrigeration: Pulse tube + dilution + adiabatic
- Vibration damping: <1nm displacement="" during="" li="" operation="">
- Cool-down time: 36 hours to reach operating temp
3. AI/Quantum Interface
The gold-colored bridges between ① and ⑥ show:
- Latency: 11ns quantum-classical roundtrip
- Data bandwidth: 28Gbps per channel
- Power consumption: 4.2mW per qubit
Manufacturing Note: Each processor requires 14 weeks to assemble, including:
- 3 weeks for qubit fabrication
- 6 weeks for cryogenic assembly
- 5 weeks for testing/calibration
