The Quantum Advantage Is Real — But There’s a Catch

Researchers at Freie Universität Berlin have developed decoded quantum interferometry, a new approach that combines quantum computing with error-correcting codes to tackle difficult optimization problems.

In a theoretical model, their algorithm achieves a performance that classical methods cannot efficiently match, providing a rigorous example of quantum advantage. The result is an important conceptual milestone — but turning this mathematical advantage into something practical on real quantum hardware remains a major challenge
