Insider Brief
Quantinuum researchers demonstrated an exponentially growing quantum advantage in a game that can be verified efficiently without relying on unproven computational-hardness assumptions.
Experiments on Quantinuum’s trapped-ion H2 systems used thousands of circuits and as many as 55 qubits, producing scores above the best possible classical limit.
The test still requires trusted components, while larger demonstrations will likely depend on improved hardware and quantum error correction.
A Quantinuum-led research team has demonstrated an exponentially widening gap between quantum and classical strategies in a test designed to verify quantum behavior without relying on unproven assumptions about computational difficulty.
