Decomposing Gradient Suppression in Barren Plateaus: Activity, Sign Organization, and Coupling
Pilsung Kang
Barren plateaus (BPs) are conventionally characterized by suppressed gradient variance, but this aggregate description does not reveal how the loss of gradient signal is composed a…
Implementing Pearl's -Calculus on Quantum Circuits: A Simpson-Type Case Study on NISQ Hardware
Pilsung Kang
Distinguishing correlation from causation is a central challenge in machine intelligence, and Pearl's -calculus provides a rigorous symbolic framework for reasoning a…
Quantum Entanglement as Super-Confounding: From Bell's Theorem to Robust Machine Learning
Pilsung Kang
Bell's theorem reveals a profound conflict between quantum mechanics and local realism, a conflict we reinterpret through the modern lens of causal inference. We propose and comput…
Emergent Bifurcations in Quantum Circuit Stability from Hidden Parameter Statistics
Pilsung Kang
The compression of quantum circuits is a foundational challenge for near-term quantum computing, yet the principles governing circuit stability remain poorly understood. We investi…
