依存关系与后果
Quantum technology depends on rare materials, specialised components, cryogenics, lasers and scarce expertise, and its effects reach every system that relies on cryptography, precise timing or navigation. This page sets out the causal, physical, economic and social links between quantum technologies and other 系统, how disruption could travel along them and how the platform analyses them. A dependency map describes connections; it is not a forecast of when any capability will arrive.

Upstream dependencies.
| 依赖关系 | 为何重要 | 风险暴露 |
|---|---|---|
| Cryogenics and helium | Many qubit technologies operate near absolute zero | Specialised refrigeration and constrained helium supply |
| Lasers, photonics and vacuum 系统 | Control and readout for trapped ions, atoms and photons | Few specialised suppliers |
| Advanced materials and fabrication | Superconducting circuits, isotopically pure materials, detectors | Concentrated manufacturing capacity |
| Classical computing and control electronics | Error correction and control require fast classical processing | Shares supply chains with semiconductors |
| Skilled people | Physics, engineering and software expertise | Small, internationally mobile talent pool |

Downstream consequences.
Cryptography
Communications, payments, software updates and identity that rely on public-key cryptography must migrate before a capable quantum computer exists.
Precision
Quantum clocks and sensors could reduce dependence on satellite navigation, which matters for telecoms, power grids and finance.
Strategic competition
Export controls, research security and concentration of capability shape who benefits and who is exposed.
Mechanisms.
The cryptographic channel is the clearest. Many 系统 share the same algorithms and libraries, so a weakness in one class of algorithm is a common-mode failure across sectors. Long-lived devices, embedded systems and archived data extend exposure far into the future, and a migration is only as strong as the slowest supplier. 支付与市场基础设施 at The Global Risks Alliance (GRA) examines what this means for financial plumbing.
A second channel is expectation. Overstated claims can redirect investment and policy, and a correction can strand both. The platform therefore reports demonstrated results separately from projections; see 量子计算 and responsible quantum innovation.
问题与解答。
Is a dependency map a forecast of when quantum computers will break encryption?
Why does the slowest supplier matter?
Why are skills a dependency?
