本文报道了用单光子激发经典热场获得量子光态的实验实现和层析分析。这样的状态，虽然完全不相干，但具有可调的量子化程度，这里利用它来对为证明和测量状态非经典性而提出的一些标准进行严格的实验测试。这些状态的量子特性也通过评估它们可以产生的纠缠量以量子信息的形式给出。
We report the experimental realization and tomographic analysis of quantum light states obtained by exciting a classical thermal field by a single photon. Such states, although completely incoherent, possess a tunable degree of quantumness which is here exploited to put to a stringent experimental test some of the criteria proposed for the proof and the measurement of state nonclassicality. The quantum character of the states is also given in quantum information terms by evaluating the amount of entanglement that they can produce.
