Exploring Rabi Oscillations, Maximally Entangled States and Perfect Teleportation in the Anti-Jaynes-Cummings Interaction: Insights into Quantum Dynamics and Entanglement Applications

This study presents a method for producing maximally entangled qubit states, also known as entangled anti-polariton qubit states, in the anti-Jaynes-Cummings interaction mechanism. We show that, in an initial vacuum-field, the time evolution of entanglement in the anti-Jaynes-Cummings interaction process takes the same form as in the Jaynes-Cummings interaction process, and that Rabi oscillations in a cavity mode in the anti-Jaynes-Cummings interaction process occur in the reverse sense relative to the Jaynes-Cummings interaction process. We demonstrate quantum teleportation of an atomic quantum state using the created anti-polariton qubit state as one of the initial qubits. We accomplish a perfect maximal teleportation fidelity of unity by employing an entanglement swapping procedure.
