In this paper, a new state called superposition of multiple-photon-added two-mode squeezed vacuum state (SMPA-TMSVS) is introduced by adding the multiple photons to both modes of a two-mode squeezed vacuum state (TMSVS). We explicitly investigate the degree of quantum entanglement, the Einstein–Podolsky–Rosen (EPR) correlation and the quantum steering in the SMPA-TMSVS. The results show in the SMPA-TMSVS that the degree of entanglement and the EPR correlation can be enhanced by nonlocal adding photons to a TMSVS. The quantum steering appears in the SMPA-TMSVS in case the superposition of single-photon addition [Formula: see text], in which mode [Formula: see text] can steer mode [Formula: see text]. By using the SMPA-TMSVS as an entangled resource, the quantum teleportation process is studied in detail based on the Vaidman–Braunstein–Kimble (VBK) protocol.

多光子添加双模压缩真空态叠加中的量子纠缠和隐形传态

在本文中,通过将多个光子添加到双模压缩真空态 (TMSVS) 的两个模式中,引入了一种称为多光子叠加双模压缩真空态 (SMPA-TMSVS) 的新状态。我们明确研究了 SMPA-TMSVS 中的量子纠缠程度、Einstein-Podolsky-Rosen (EPR) 相关性和量子转向。结果表明,在 SMPA-TMSVS 中,纠缠度和 EPR 相关性可以通过将光子非局部添加到 TMSVS 来增强。SMPA-TMSVS中出现了量子转向,以防单光子叠加[公式:见文],其中模式[公式:见文]可以引导模式[公式:见文]。通过使用 SMPA-TMSVS 作为纠缠资源,
