Quantum software: high-level modeling, circuit synthesis and compilation

Request platform access

The documentation is public. Running the platform requires an invited account; the current registration page says free noncommercial access is unavailable.

What has been demonstrated

A Classiq–Rolls-Royce preprint studies a hybrid fluid-flow solver through numerical simulation and compiled resource estimates. In its tested case, approximation reduces single-qubit rotation requirements by more than an order of magnitude while preserving convergence.

What remains unresolved

The fluid-flow result is a small numerical study and resource estimate. It does not establish industrial quantum speedup or successful execution of that application on useful fault-tolerant hardware.
