Agentic AI for Scientific Reasoning in Autonomous Quantum Sensing Experiments
Takuya Isogawa, Ryotaro Okabe, Nutdech Phadetsuwannukun +2
We implement an agentic AI workflow built around a large language model (LLM) agent for autonomous experiments with nitrogen-vacancy (NV) centers in diamond. NV centers are a widel…
Approaching the Limit in Multiparameter AC Magnetometry with Quantum Control
Takuya Isogawa, Zhiyao Hu, Ayumi Kanamoto +9
Simultaneously estimating multiple parameters at the ultimate limit is a central challenge in quantum metrology, often hindered by inherent incompatibilities in optimal estimation…
Optimal Control of Coupled Sensor-Ancilla Qubits for Multiparameter Estimation
Ayumi Kanamoto, Takuya Isogawa, Shunsuke Nishimura +2
Designing optimal control for multiparameter quantum sensing is essential for approaching the ultimate precision limits. However, analytical solutions are generally available only…
Entanglement-assisted multiparameter estimation with a solid-state quantum sensor
Takuya Isogawa, Guoqing Wang, Boning Li +5
Quantum multiparameter estimation promises to extend quantum advantage to the simultaneous high-precision measurements of multiple physical quantities. However, realizing this capa…
Control incompatibility in multiparameter quantum metrology
Zhiyao Hu, Shilin Wang, Linmu Qiao +6
In practical applications like quantum sensing and quantum imaging, there is often a necessity to estimate multiple parameters simultaneously. Although the ultimate precision limit…
Optimal Quantum Purity Amplification
Zhaoyi Li, Honghao Fu, Takuya Isogawa +2
Quantum purity amplification (QPA) provides a novel approach to counteracting the pervasive noise that degrades quantum states. We present the optimal QPA protocol for general quan…
Interferometry of quantum correlation functions to access quasiprobability distribution of work
Santiago Hernández-Gómez, Takuya Isogawa, Alessio Belenchia +4
The Kirkwood-Dirac quasiprobability distribution, intimately connected with the quantum correlation function of two observables measured at distinct times, is becoming increasingly…
