摘要

我们展示了基于光束移位器的偏振纠缠光子对源的实验实现。下变频光子是在非退化和 0 型过程中通过自发参数下变频发射的。我们获得了 F = 0.975 ± 0.004 的状态保真度，并以 $\mathcal {S}=2.75\pm 0.01$ 违反了 Clauser-Horne-Shimony-Holt (CHSH) 不等式。我们的光源还利用薄晶体的大量空间模式，将其应用于量子成像。我们估计我们的源可以产生 550 ± 12 种空间模式。

Polarization-entangled photon-pair source using beam displacers and thin crystals.

We present an experimental implementation of a polarization-entangled photon-pair source based on beam displacers. The down-converted photons are emitted via spontaneous parametric downconversion in a non-degenerate and type-0 process. We obtain a state fidelity of F = 0.975 ± 0.004 and violate a Clauser-Horne-Shimony-Holt (CHSH) inequality with $\mathcal {S}=2.75\pm 0.01$. Our source also uses thin crystals for applications in quantum imaging, taking advantage of the large number of spatial modes. We estimate that our source could produce 550 ± 12 spatial modes.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
