Detection of Zak phases and topological invariants in a chiral photonic quantum walk

2016 · arXiv (Cornell University)

Topological insulators are fascinating states of matter exhibiting protected edge states and robust quantized features in their bulk. Here, we propose and validate experimentally a method to detect topological properties in the bulk of one-dimensional …

Characterizing out-of-distribution generalization of neural networks: application to the disordered Su–Schrieffer–Heeger model

2024 · Machine Learning Science and Technology

Abstract Machine learning (ML) is a promising tool for the detection of phases of matter. However, ML models are also known for their black-box construction, which hinders understanding of what they learn from the data …

PulserDiff: a pulse differentiable extension for Pulser

2025 · arXiv (Cornell University)

Programming analog quantum processing units (QPUs), such as those produced by Pasqal, can be achieved using specialized low-level pulse libraries like Pulser. However, few currently offer the possibility to optimize pulse sequence parameters. In this …
