Stacking the Deck: Tunable Trainability in Stacked LCUs
arXiv:2607.24686v1 Announce Type: cross Abstract: Variational quantum circuits have been central to many proposed near-term applications of quantum computing, but a growing body of evidence suggests that trainability and quantum advantage are fundamentally at odds: ans"atze expressive enough to resist efficient classi
