Multi-parameter estimation enhanced by level crossing Hamiltonian structure with Bayesian feedback
Ryo Tatsumi, Le Bin Ho, Hiroaki Matsueda
Level crossings, where two quantum energy levels intersect, are ubiquitous in quantum systems and play a central role in controlling quantum dynamics. In this study, we establish a…
Interference-induced state engineering and Hamiltonian control for noisy collective-spin metrology
Le Bin Ho, Vu Xuan Tung Duong, Nozomu Takahashi +1
Interference provides a fundamental mechanism for generating and manipulating entanglement in many-body quantum systems. Here, we develop an interference framework in which the non…
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 +2
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…
