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 …

Probing quantum entanglement from magnetic-sublevels populations: beyond spin squeezing inequalities
2022 · arXiv (Cornell University)
Spin squeezing inequalities (SSI) represent a major tool to probe quantum entanglement among a collection of few-level atoms, and are based on collective spin measurements and their fluctuations. Yet, for atomic ensembles of spin-$j$ atoms …

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 …

Many-body quantum resources of graph states
2025 · Reports on Progress in Physics
Abstract Characterizing the non-classical correlations of a complex many-body system is an important part of quantum technologies. An ideal tool for this task would scale well with the size of the system, be easily computable …
