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…
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.…
Advancing quantum process tomography through quantum compilation
Huynh Le Dan Linh, Vu Tuan Hai, Le Bin Ho
Quantum process tomography (QPT) plays a central role in characterizing quantum gates and circuits, diagnosing quantum devices, calibrating hardware, and supporting quantum error c…
Squeezing-induced quantum-enhanced multiphase estimation
Le Bin Ho
We investigate how squeezing techniques can improve the measurement precision in multiphase quantum metrology. While these methods are well-studied and effectively used in single-p…
tqix: A toolbox for Quantum in X: Quantum measurement, quantum tomography, quantum metrology, and others
Le Bin Ho, Kieu Quang Tuan, Hung Q. Nguyen
We present an open-source computer program written in Python language for quantum measurement and related issues. In our program, quantum states and operators, including quantum ga…
