Example Sentences:

	1.	And the spdc has also been widely studied for its entanglement of time , space , polarization , and energy 另外，参量下转换产生的光子对具有时间、空间、偏振、能量等多种纠缠，因而在理论和实验上都得到了广泛的研究。
	2.	Because spdc creates photons in pairs , if one photon is found in one arm of the twin - photon , we know there must exists a single - photon state in another arm . so , we can assure when the single - photon state generate without detecting it 其中，自发参量下转换因其成对的产生下转换光子，可以通过探测其中之一来确认另一个是否为单光子态，这样就可以在不破坏单光子的情况下确认单光子的存在。
	3.	Experimental results of four - photon de broglie wavelength measurement are analyzed based on a local description for the quantum state and optical field of photon pairs generated from spontaneous parametric down - conversion ( spdc ) 摘要采用对自发参量下转换过程产生的光子对的量子态和光场的非纠缠态描述，分析了由自发参量下转换过程产生的四光子的德布罗意波长测量的实验，得到了与实验观测相一致的结果。
	4.	There are many ways to generate single - photon state , e . g . attenuated laser , quantum dot , pulsed excitation of a single dipole , single nitrogen - vacancy color center in a diamond nanocrystal , cavity - qed and spontaneous parametric down - conversion ( spdc ) 目前有多种方案可以制备单光子态，如直接将激光衰减至单光子水平、量子点、单荧光分子以及金刚石纳米颗粒中的n - v色心、腔qed及自发参量下转换等。
	5.	In order to get single - photon state and reconstruct its wigner function , the two aspects , spdc of pulse pumped nonlinear phase match type i bbo crystal and reconstruction of wigner function of quantum state , are studied in this thesis . 1 本文是单光子态制备及其wigner函数重构课题中的部分内容，主要包括两个方面内容，即脉冲抽运的类非共线相位匹配bbo晶体的自发参量下转换过程和利用量子层析摄影术重构光量子态的wigner函数。
