Time-Reversal Selection Rules for Quantum Error Correction
We apply time-reversal symmetry to quantum codes and show that it imposes parity selection rules on the physical error algebra. A time-reversal-invariant logic…

Fundamental limits of parameter estimation with heralded optical non-Gaussian states generated from Gaussian resources
Non-Gaussian states can exhibit large quantum Fisher information (QFI) in quantum sensing. In optical systems, however, its generation is often probabilistic v…

Persistent homology broadens the controllable subspace in human structural connectomes
Network control theory applied to structural connectomes typically ranks brain regions as candidate driver nodes by their structural connectivity strength, and…

Approximate Quantum Error Correction at Chiral Topological Edges
Topologically ordered phases naturally realize quantum error correction through nonlocal encoding of quantum information. More recently, conformal field theori…

A Quantum Circuit Framework for Protein Ensemble-Level Energetics
Proteins occupy heterogeneous free-energy landscapes in which high-entropy ensembles converge toward compact, low-energy basins with multiple sub-states. Molec…

Scaling an Autoregressive Transformer for Single-Cell Generation
We study a self-supervised generation task for single-cell gene expression vectors: given a set of vectors from a cell type, we aim to generate additional gene…

Millisecond-Scale Neural Operator Surrogates for Double-Null Free-Boundary Grad-Shafranov Equilibria
The Grad-Shafranov (GS) equation governs ideal magnetohydrodynamic equilibrium in tokamak plasmas. Free-boundary GS solvers are central to diverted-equilibrium…

Error-detected surgery on Iceberg codes
We construct explicit error-detecting surgery gadgets---small systems of auxiliary qubits and checks---for the high-rate Iceberg codes $[[2N,2N-2,2]]$, to perf…

EpiBench: Can LLMs Understand Epitopes for Antibody Drug Discovery?
Epitopes determine where antibodies bind antigens and shape downstream therapeutic properties such as functional blockade and escape resistance, making epitope…

A Low-Power Wearable Respiratory Sensor for Non-Invasive Stress Monitoring
Respiration provides a continuously available window into physiological state and behavior. However, monitoring it outside controlled settings remains challeng…

Population Structures with Positive Feedback and Asymmetric Division
In bioreactor experiments, budding yeast can manifest stable metabolic oscillations. In some instances these oscillations involve the cell cycle and are associ…

The Cost of Binarizing Survival Outcomes in Clinical Prognostic Modeling
Survival analysis is an established framework for analyzing time-to-event data, yet many clinical machine learning studies still binarize the outcome before mo…

Spatial proteomics guided by H&E-based AI reveals recurrence-risk niches in triple-negative breast cancer
Deep learning models can predict cancer recurrence from H&E stained slides, but the localized molecular states underlying these predictions remain largely…
