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. By quantifying coherence, 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 system: the nitrogen-vacancy (NV) center in pure diamond. The experimental data agrees well with theoretical expectation. The natural indivisible three dimension of spin-1 quantum state shows the principle of coherence and superposition not resulting from entanglement or non-locality. The entanglement-enhanced phase estimation in NV-diamond system will also be reported.
