Measurement Geometry as a Resource for Certifying Network Nonlocality
Leon Adachi, Le Bin Ho
Quantum networks can exhibit nonclassical correlations that cannot be explained by classical models with independent sources. While the role of entanglement is well understood, the…
Boosting the performance of a Lipkin-Meshkov-Glick quantum battery via symmetry-breaking quenches or a single-mode bosonic charger
Le Bin Ho, Duc Tuan Hoang, Tran Duong Anh-Tai +3
We explore the operation of quantum batteries in the Lipkin-Meshkov-Glick (LMG) model, when they are charged either through a sudden quench in the magnetic field strength or by cou…
Trade-off relation between integrated metrological gain and local dissipation in magnetic-field sensing by quantum spin ensemble
Nozomu Takahashi, Le Bin Ho, Hiroaki Matsueda
Quantum metrology plays a central role in precision sensing, where quantum enhancement of detection performance is crucial for both fundamental studies and practical applications.…
Optimized quantum sensor networks for ultralight dark matter detection
Adriel I. Santoso, Le Bin Ho
Dark matter (DM) remains one of the most compelling unresolved problems in fundamental physics, motivating the search for new detection approaches. We propose a network-based quant…
