Quantum Estimation with State Symmetry-Induced Optimal Measurements
Jia-Xuan Liu, Hai-Long Shi, Chunfeng Wu +1
A central challenge in quantum metrology is identifying optimal measurements that saturate the quantum Cramer-Rao bound under realistic constraints, e.g., local measurements. We sh…

Optimal Local Measurements in Single-Parameter Quantum Metrology
Jia-Xuan Liu, Jing Yang, Hai-Long Shi +1
Quantum measurement plays a crucial role in quantum metrology. Due to the limitations of experimental capabilities, collectively measuring multiple copies of probing systems can pr…

Quantum control limited by quantum decoherence
Fei Xue, S. X. Yu, C. P. Sun
We describe quantum controllability under the influences of the quantum decoherence induced by the quantum control itself. It is shown that, when the controller is considered as a…
