On The Most Discriminative Boolean Functions for Correlated Sources
Jun Chen, Shun Watanabe, Lei Yu
The paper investigates which pairs of Boolean functions best separate two correlated binary sources by maximizing Kullback-Leibler divergence (and Fisher information), proving that…
Area-Information Trade-Offs in Acceleration Radiation from Atoms Falling into Black Holes
Yusef Maleki, Gustavo Valdivia-Mera, Carlos R. Ordonez +2
The paper develops a geometric framework that relates the change in a black hole’s horizon area to limits on the amount of information carried by acceleration radiation from atoms…
Recovering Coherent Errors from Randomized-Compiling Labels
Kushagra Vyas
The paper shows that the random gate choices (labels) used in randomized compiling retain full information about coherent gate errors, and by correlating these labels with measurem…
Counterfactual Quantum Sensing: What Interaction-Free Measurement Can and Cannot Buy
Christoph F. Wildfeuer
The paper analyzes interaction‑free (counterfactual) quantum sensing as a channel‑estimation problem, showing that such interferometric schemes provide no advantage for estimating…
PIcsC: Partitioning-Induced Covariate Shift Correction
Behraj Khan, Behroz Mirza, Syed Ahmad Chan Bukhari +1
The paper introduces PIcsC, a Fisher information‑based regularization method that corrects covariate shift caused by data partitioning in both centralized (e.g., cross‑validation)…
Universal Operational Privacy in Distributed Quantum Sensing
Min Namkung, Dong-Hyun Kim, Seongjin Hong +3
The paper proposes a universal, experimentally accessible privacy criterion for distributed quantum sensing based on the Fisher information matrix, and demonstrates experimentally…
