According to Quantum Computing Report, Q-CTRL and IBM reported a 3,000x speedup when simulating the Fermi-Hubbard model on 120 qubits using runtime error-suppression techniques, describing the result as practical quantum advantage.
The quantum advantage framing is a company claim and remains subject to independent verification. The result nevertheless highlights the role of error suppression in near-term quantum computing.
