Abstract
Quantum teleportation, a cornerstone of quantum communication and quantum computing, relies on strong entanglement to transfer quantum information with high fidelity. However, the efficiency and accuracy of teleportation are often constrained by the degree of squeezing in the entangled states. This article, presents a method to enhance squeezing to strengthen entanglement, finally it improves the fidelity of quantum teleportation. The proposed method applies multi-mode squeezing enhancement technique and combine it with entanglement purification, resulting in much lower quadrature variance and an optimized quantum state. By improving the squeezing process, in this article it is shown that stronger entanglement leads to more reliable and stable quantum state transfer. This proposed method is offering a potential route in the direction of high-fidelity quantum communication, scalable quantum networks, and secure quantum applications.
期刊介绍:
Papers published in the IEEE Journal of Selected Topics in Quantum Electronics fall within the broad field of science and technology of quantum electronics of a device, subsystem, or system-oriented nature. Each issue is devoted to a specific topic within this broad spectrum. Announcements of the topical areas planned for future issues, along with deadlines for receipt of manuscripts, are published in this Journal and in the IEEE Journal of Quantum Electronics. Generally, the scope of manuscripts appropriate to this Journal is the same as that for the IEEE Journal of Quantum Electronics. Manuscripts are published that report original theoretical and/or experimental research results that advance the scientific and technological base of quantum electronics devices, systems, or applications. The Journal is dedicated toward publishing research results that advance the state of the art or add to the understanding of the generation, amplification, modulation, detection, waveguiding, or propagation characteristics of coherent electromagnetic radiation having sub-millimeter and shorter wavelengths. In order to be suitable for publication in this Journal, the content of manuscripts concerned with subject-related research must have a potential impact on advancing the technological base of quantum electronic devices, systems, and/or applications. Potential authors of subject-related research have the responsibility of pointing out this potential impact. System-oriented manuscripts must be concerned with systems that perform a function previously unavailable or that outperform previously established systems that did not use quantum electronic components or concepts. Tutorial and review papers are by invitation only.
