• Abstract: This study aims to provide insights into various aspects of quantum chaos and teleportation by implementing the recently developed Wormhole-Inspired Teleportation Protocol (WITP). We commence by constructing an analog of a traversable wormhole utilizing the Sachdev-Ye-Kitaev (SYK) model in conjunction with the Thermofield Double (TFD) state framework, implemented within a quantum circuit. Subsequently, we manipulate various parameters, including temperature ($\beta$) and the location of the message qubit, and compare the fidelity result with that of the Transverse Field Ising Model (TFIM)-based wormhole-inspired teleportation protocol. Our findings demonstrate that the SYK-based protocol achieves a higher fidelity of states in comparison to the TFIM counterpart. We further analyze the protocol for different values of $\beta$ and the SWAP operator. These findings are attributed to the emergence of random matrix ensembles via random phase theory within the dynamics of the SYK model, which is characterized by pronounced chaotic behavior. A significant outcome of our investigation is initializing the message as a two-qubit Bell state, followed by teleportation across the system. We introduce a Pauli stabilizer-based fidelity measure to diagnose the teleportation characteristics. This yields a considerable enhancement in fidelity relative to the single-qubit variant of the protocol. Finally, we analyze the temporal fluctuation of fidelity for both single-qubit and two-qubit message across the channel, contributing to a deeper understanding of quantum teleportation dynamics.
