热光双光子干涉

Two-photon interference with thermal light

Giuliano Scarcelli, Alejandra Valencia, Yanhua Shih

摘要:

纠缠态的研究极大地提高了人们对双光子干涉的基本认识。双光子干涉不是两个光子的干涉,而是不可分辨的双光子振幅叠加的结果。然而,双光子振幅的概念通常仅限于纠缠光子的情况。在这封信中,我们报告的实验研究,可能会扩展这一概念的一般情况下,独立的光子。该实验还显示了有趣的实际应用的可能性,获得高分辨率的干涉图案与热源。

英文摘要:

The study of entangled states has greatly improved the basic understanding about two-photon interferometry. Two-photon interference is not the interference of two photons but the result of superposition among indistinguishable two-photon amplitudes. The concept of two-photon amplitude, however, has generally been restricted to the case of entangled photons. In this letter we report an experimental study that may extend this concept to the general case of independent photons. The experiment also shows interesting practical applications regarding the possibility of obtaining high resolution interference patterns with thermal sources.
