Abhängigkeiten und Folgen

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 Systeme, 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.

03What depends on quantum outcomes

Downstream consequences.

Digital trust

Cryptography

Communications, payments, software updates and identity that rely on public-key cryptography must migrate before a capable quantum computer exists.

Timing and navigation

Precision

Quantum clocks and sensors could reduce dependence on satellite navigation, which matters for telecoms, power grids and finance.

Economy and security

Strategic competition

Export controls, research security and concentration of capability shape who benefits and who is exposed.

04How disruption could travel

Mechanisms.

The cryptographic channel is the clearest. Many Systeme 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. Zahlungs- und Marktinfrastruktur 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 Quantencomputing and responsible quantum innovation.

05Methode

How dependencies are analysed.

Analysis uses Wahrscheinlichkeit und Statistik to treat uncertain timelines as distributions rather than dates, and cryptographic analysis to map where vulnerable algorithms sit. Each map states its assumptions and uncertainty; see Methoden und Unsicherheit. Back to Überblick über das Feld.

06Fragen

Fragen und Antworten.

Is a dependency map a forecast of when quantum computers will break encryption?
No. It shows where systems would be exposed and how disruption could spread. Timelines are uncertain and are reported as such.
Why does the slowest supplier matter?
Because a system is only as secure as its weakest component. If one supplier in a chain has not migrated, data passing through it may remain exposed.
Why are skills a dependency?
Because the field needs rare combinations of physics, engineering and software expertise, and a shortage slows research, deployment and the cryptographic migration alike. See Quanten-Fachkräfte.
