What does it take for a quantum computer to actually be "quantum"? Building a quantum computer is one thing. Showing that it is genuinely using quantum mechanics is another. A convincing demonstration of “quantumness” should show that the machine is exploiting properties that truly distinguish quantum computation from classical computation. In a new result, just published in @​NatureComms, our researchers focused on one of those defining properties: superposition. The team constructed a game where quantum mechanics provides a provable advantage over classical approaches. Thanks to our world-class hardware, the performance gap between the best possible classical system and our System Model H2 grew wider and wider as the test became more difficult.

A new experiment tests what makes a quantum computer genuinely quantum by using a simple game that demonstrates a provable advantage from quantum superposition, without relying on entanglement or assumptions about classical computational difficulty. The test was demonstrated on Quantinuum’s System Model H2.
