New framework breaks one-dimensional expressibility-trainability tradeoff in quantum circuits

Researchers have demonstrated that the expressibility and trainability of parameterized quantum circuits (PQCs) are not bound by a one-dimensional tradeoff. They propose a new framework that separates entangling power (EP) and entangling-power deviation (EPD) into distinct design dials. This allows for the creation of highly expressive PQCs that maintain trainability by reaching high coverage before barren-plateau conditions emerge. AI
