内容摘要：Quantumcoherence is the fundamental reason for the significant phenomena differingfrom our everyday life such as uncertainty principle, entanglement andcontextuality in quantum mechanics. Recently, the problem of quantifyingcoherence has been attracting a great deal of interests. We will report somemain progresses in research of this field. As an example, we observe thatquantum coherence as resource should satisfy relations due to uncertaintyprinciple in entropic representation. Experimentally, we demonstrate the coherenceresource and entropic uncertainty relations in three measurements bases by anatural three dimensional solid-state systems: the nitrogen-vacancy (NV) centerin pure diamond. The experimental data agrees well with theoreticalexpectation. In a different experiment, we show that valley qubit candemonstrate the quantum coherence.
