Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final layers really mattering. As a result, deep quantum circuits behave more like shallow ones. This limits what current quantum computers can realistically achieve.
