Physics and quantum science
Physics studies matter, energy and their interactions, from fundamental particles to large-scale systems. It provides the governing equations used across hazard modelling, sensing and engineering. Quantum Technologies stewards this page for the Nexus Consortium.

The short answer.
Physics studies matter, energy and their interactions, from fundamental particles to large-scale systems. Physical principles constrain hazard models, sensor design and engineering limits. In the Nexus Consortium, Quantum Technologies stewards its canonical page, and 2 other platforms apply it, including Data and Compute as well as Space and Earth Observation.

What physics and quantum science covers.
- 01
Core methods
theoretical modelling; numerical simulation; controlled experimentation; statistical mechanics; signal and measurement analysis; quantum mechanical modelling.
- 02
Data and instruments
laboratory instruments; particle and radiation detectors; precision sensors; observatories; simulation outputs.
- 03
Validation
Theories are tested by reproducible experiments and precise measurement. Numerical codes are verified against analytical solutions and benchmark problems.
- 04
Limits
Idealised models may omit friction, heterogeneity or coupling present in real systems. Scale transfer from laboratory to field introduces error.
- 05
Use in risk decisions
Physical principles constrain hazard models, sensor design and engineering limits. They help distinguish physically plausible scenarios from implausible ones.

Physical limits and timing.
Physics enters risk work through the limits it places on technologies (the error rates of quantum devices, the physics of space weather, the thermodynamics of cooling) and through precision timing and navigation that many networks share. A geomagnetic storm or timing-signal disruption is a physics event with consequences in power, telecoms and finance at once.
- Separate demonstrated device performance from roadmap claims.
- Treat shared timing and navigation signals as a common dependency.
- Use physical constraints to bound model outputs in other fields.
- Applications on Quantum and Data and Compute.

Terms used on this page.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Landauer limit | The minimum energy theoretically required to erase one bit of information at a given temperature. |
| Power density | The power used per unit of area or volume, which drives cooling needs. |
| Randomised benchmarking | A method that estimates average gate error by applying random sequences of operations. |
| Bell test | An experiment testing whether correlations between particles exceed classical limits. |
