Paper: Preventing Barren Plateaus in Continuous Quantum Generative Models
What they're saying
They proposed a VQC architecture that AVOIDS BARREN PLATEAUS!! This suggests QUANTUM ADVANTAGE on NISQ devices!!
The Critique
They never address the elephant in the room: trainability vs expressibility! Usually, avoiding barren plateaus means restricting what your model can express! So is this model trainable because it's... simple? Like, classically-simulable simple?! They claim robustness against 'current' classical methods, but 'current' is doing a lot of work here!
Why It Matters
If the model is both trainable AND classically simulable, it undermines claims of quantum advantage. The field has seen many 'quantum advantage' claims fall to improved classical algorithms.
What They Missed
They don't quantify how much of the 'quantum advantage' comes from the data encoding versus the variational circuit.
The Big Question
Is the model avoiding barren plateaus by sacrificing expressibility, making it classically simulable by methods yet to be discovered?
