Q-CTRL ran a 120-qubit Fermi-Hubbard simulation on the IBM cloud in two minutes. The state-of-the-art classical solver on an HPC cluster needed over a hundred hours to land inside one percent of the same trajectory.

Every quantum roadmap signed into 2029 priced fault tolerance as the gating event. Practical advantage was supposed to wait for the surface-code generation, the million-qubit substrate, the logical-layer error correction. Q-CTRL routed around the calendar with runtime error suppression on a 120-qubit NISQ chip, beating the best classical algorithm anyone ships on a problem materials science actually pays to solve.

The threshold the field priced as 2029 cleared this week on hardware the same field still files under demo.
