Barren Plateaus as Destructive Interference: A Diagnostic Framework and Implications for Structured Ansatzes

Pilsung Kang

Barren plateaus (BPs) are usually described by the exponential suppression of gradient variance, but the mechanism by which gradient signal disappears remains unclear. We show that…

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…

COUNTDOWN: Contextually Sparse Activation Filtering Out Unnecessary Weights in Down Projection

Jaewon Cheon, Pilsung Kang

The growing size of large language models has created significant computational inefficiencies. To address this challenge, sparse activation methods selectively deactivates non-ess…

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…
