We are building for the machine that does not exist yet.

Systems built so the cryptographic primitive is a swappable component: it can be replaced without rewriting what sits on top of it.

• Cryptography treated as a component, not an assumption
• The primitive replaceable without rewriting above it
• The preparation that survives a real migration deadline

A payments platform signs every transaction with one algorithm, called directly from eleven services. When a post-quantum standard is adopted, a crypto-agile system changes the primitive in one place, runs old and new signatures side by side through the migration, and retires the old one without rewriting what sits on top.

Optimisation problems written down in a form that names the solver explicitly. The classical solver runs them today, and the problem statement is already separable from the thing that solves it.

• The problem stated separately from the solver
• The classical solver runs it today
• A different class of hardware can be swapped in when it is worth using

A fleet’s nightly routing is written as an optimisation problem that names its solver. Today a classical solver answers it in minutes. When other hardware is worth testing, the same problem statement goes to it in parallel and the answers are compared, without touching the application that uses them.

Orchestration across classical and quantum resources so each part of a workload runs where it actually belongs, on the honest position that almost everything belongs on classical hardware today.

• Workloads split across classical and quantum resources
• Each part runs where it actually belongs
• The value is knowing precisely which parts will not, and why

A materials team’s simulation workload has thousands of steps. Profiled, one small part, the electronic structure of a single molecule, is the only one that could ever benefit from quantum hardware; everything else belongs on classical machines. The honest advice today is to run it all classically, and to know exactly which part would move, and why, when the hardware is ready.
