Industry 9
Aerospace & sovereign programmes
Aerodynamics and mission-engineering groups; national quantum programmes that own a 5 to 25-qubit machine.
The decision
When quantum CFD pays off; what to run on the installed machine now; how to schedule traffic, gates and missions.
How it is done today
Programmes wait for methods that need a hundred qubits; traffic and gates are scheduled with classical tools.
When it goes wrong A machine that is installed and idle; a CFD budget with no date on it.

What changes for you
- Circuits that run on the machine already installed: 42 working units on a 256-atom machine, coupling set by placement.
- Heavy compute inside the perimeter, with UAE residency.
- A dated answer on CFD instead of an open-ended one.
First engagement
You send Your machine’s calibration export.
You get back Its characterisation and what it can run this quarter. Two weeks.

When quantum CFD pays off, and what runs on the installed machine today
What is modelled
The cost of the flow-transport solver against its classical equivalent, as a measured scaling law.
Operational outcome
- A dated crossover for quantum CFD
- Fixed circuit depth of three entangling layers from 5 to 156 qubits
- Runs on the 5–25-qubit machine a national programme already owns
- Problem size
- 5–156 qubits · 7 quantum platforms · heavy compute inside the customer perimeter
- Scope
- A projection; no CFD advantage on present hardware is claimed.
Results, each with its baseline
