We achieved the most physically complex, publicly documented hardware demonstration of a quantum fluid simulation to date.
Moving beyond simplified, linear simulations in empty spaces, we successfully executed a 15-step nonlinear fluid benchmark. For the first time, we modeled moving fluid dynamically interacting with an embedded solid obstacle on a physical quantum device.
Embedding a physical object within a quantum grid usually requires multi-controlled quantum gates that create circuits far too deep for today's hardware to survive.
We utilized the IBM Heron R3, one of the largest and most stable superconducting quantum processors currently available.
We deployed a radically novel computational framework called the One-Step Simplified Lattice Boltzmann Method (OSSLBM).
The OSSLBM ingeniously fuses the traditionally separate collision and propagation mathematical phases into a single, unified quantum operation.
Simulating highly nonlinear Navier-Stokes problems around geometric obstacles is considered the holy grail of industrial computational fluid dynamics.
It proves that a practical algorithmic pathway now exists to move quantum computing out of theoretical academic research and directly into enterprise R&D workflows.
It maps a clear roadmap for resolving complex turbulence and solid boundaries, which is essential for analyzing chaotic airflow over commercial jet wings or hydrodynamics on massive ship hulls.
