Quantum Multiparameter Estimation Using Quantum Temporal Reference Frames

Quantum Multiparameter Estimation Using Quantum Temporal Reference Frames

In any physical experiment, we are always trying to measure a quantity. How precisely can we measure a quantity in the laboratory? This is a fundamental question addressed within the framework of quantum estimation theory. In this talk, I will first present the general concepts in quantum estimation. Then I will generalize these concepts to multiparameter quantum estimation. In this regard, after introducing quantum reference frames, I will use them as an effective tool in multiparameter quantum estimation. As a result, in this talk, while getting familiar with quantum estimation and quantum reference frames as research fields in quantum information and computation, I will show how using quantum reference frames can enhance our precision in quantum multiparameter estimation.
