报告摘要：Quantum coherence is the fundamental reason for the significant phenomena differing from our everyday life such as uncertainty principle, entanglement and contextuality in quantum mechanics. Recently, the problem of quantifying coherence has been attracting a great deal of interests, some progresses will be reported. We observe that quantum coherence as resource should satisfy relations due to uncertainty principle in entropic representation. Experimentally, we demonstrate the coherence resource and entropic uncertainty relations in three measurements bases by a natural three dimensional solid-state systems: the nitrogen-vacancy (NV) center in pure diamond. The experimental data agrees well with theoretical expectation. Also, the anisotropic Rabi model which can describe the physics of light-atom interaction in all range of strength will be reported, the simulation of the related models in various physical systems will be discussed.
