University Of Oxford Team Designs Stacked LCUs For Tunable Quantum Trainability

A polynomial gap of O(lkn²) quantum gate complexity against O(k²ln³) classical simulation cost now defines the potential of stacked linear combination of unitaries. Previously, variational quantum circuits either succumbed to barren plateaus or were easily replicated on conventional computers, offering no clear advantage. This new construction provides a tunable balance, allowing designers to systematically adjust circuit complexity for specific…
