Enhancing Squeezing to Strengthen Entanglement for High-Fidelity Quantum Teleportation

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.
