摘要:

利用贝叶斯理论分析了一种有条件地建立单模或多模光子数态的技术。我们考虑了当预告探测器是Fitch等人最近证明的时间复用光子数分辨探测器时,由非种子光学参量放大器产生的光子产生的预告N光子态[Phys. Rev. A 68,043814(2003)]。同时由Achilles等人[Opt. Lett. 28,2387(2003).]。我们发现,即使有显着的损失,预示着检测器,字段与子泊松光子数分布可以创建。我们还表明,使用这种技术创建的预示多模字段更强大的探测器损耗比单模字段。

英文摘要:

A technique for conditionally creating single- or multimode photon-number states is analyzed using Bayesian theory. We consider the heralded N-photon states created from the photons produced by an unseeded optical parametric amplifier when the heralding detector is the time-multiplexed photon-number-resolving detector recently demonstrated by Fitch, et al. [Phys. Rev. A 68, 043814 (2003).] and simultaneously by Achilles, et al. [Opt. Lett. 28, 2387 (2003).]. We find that even with significant loss in the heralding detector, fields with sub-Poissonian photon-number distributions can be created. We also show that heralded multimode fields created using this technique are more robust against detector loss than are single-mode fields.
