Pre-Asymptotic Trainability in Photonic Variational Circuits under Postselection
Yichen Xie, Cassandre Notton, Jean Senellart
Barren plateaus (BP) in variational quantum circuits are commonly attributed to strong mixing dynamics that cause gradient variance to vanish exponentially with system size. Passiv…
