Theoretical Feasibility of Quantum Teleportation in the Presence of Quantum Oscillations Under Intrinsic Decoherence

Abstract

Quantum teleportation, utilizing pre-shared entanglement, plays a vital role in the secure transmission of quantum information. In this study, we explore the feasibility of single-qubit quantum teleportation in the presence of intrinsic decoherence, utilizing two dissimilar coupled qubits that exhibit quantum oscillations. Additionally, we explore quantum remote sensing at the destination of a single-qubit quantum teleportation process, employing quantum remote estimation to assess the teleported state using Quantum Fisher Information (QFI). Furthermore, we analyze the system’s dynamics within the current model by investigating non-Markovianity witnessed through the QFI, a critical aspect in quantum communication. By appropriately adjusting system parameters such as the Josephson energies of the qubits and the energy of the mutual coupling between qubits, quantum teleportation, and quantum remote sensing can be enhanced under quantum oscillations.
