Preparing a Quantum Hybrid Channel Based on the Coupled Multifluxonium System for Optimal Quantum Teleportation

ABSTRACT In this research, we explore a novel hybrid channel architecture for preserving entanglement, specifically tailored for quantum communication applications. Our design incorporates a coupled multifluxonium system, consisting of two fluxonium qubits interconnected through capacitive coupling, considering the intricate dynamics of quantum properties. The hybrid channel exhibits a unique composition, featuring both thermal and local components, which dynamically evolve over time. To evaluate its performance, we employ a comprehensive set of metrics, including quantum statistical speeds (quantum Fisher information and Hilbert–Schmidt speed), fidelity, average fidelity, relative entropy of entanglement, Bures distance, and Von Neumann entropy. These measures provide a thorough understanding of the channel's effectiveness in transmitting quantum states. Our findings reveal that this hybrid channel achieves maximum entanglement and mixedness of the states, showcasing its exceptional capability for successful quantum state transmission. This breakthrough holds immense potential for advancing quantum communication and computing technologies. This study contributes to the development of robust quantum information processing systems, paving the way for future advancements in the field. We also describe a practical implementation of quantum teleportation based on the current channel via quantum state tomography.
