Abstract We demonstrate that oscillating two-spin molecule can lead to optimal teleportation in noisy environment. In order to teleport one and two qubit states through, a scheme is proposed for quantum channel where is induced from an oscillating two-spin molecule in present field. Given that biological systems are hot and with extremely high levels of noise, we suppose that the initial state of the molecule is its separable state as some as it is coupled to a hot and noisy environment, in which no entanglement can recur. When the distance between the spins is oscillating, generation of entanglement can persist. The model reveals that the dynamics of entanglement depends crucially on oscillating molecule initial conditions and the spin distance can be utilized as control parameters for optimal teleportation. We can observe that the increase of the initial spin distance has led to the decrease in the value of the quantum correlations and average fidelity. The results also provide that the average fidelity can have larger than 23 in front of the noise environment with oscillating molecule. Success in quantum states transfer with the oscillating molecule in present noisy environment establishes the importance of studying biological systems.

1 Introduction In early years, studying the role of quantum correlation in specific biological scenarios has attracted the attention of many people [1–5]. Observable quantum effects in biological matter are naively expected to be strongly suppressed. A significant restriction on biological systems is environmental noise; therefore they tolerate extremely high levels of noise [1, 6, 7]. On the other hand, quantum correlation is very sensitive to noise and implicates particular conditions to be guarded, in particular very good insulation. Recent studies have shown that environmental noise, together with the driven motion, plays a constructive role by periodically resetting the system [8]. Entanglement can be preserved and even generated with the heat exchange between molecular machines and environment [9]. In recent years, there has been an ongoing effort to high quantum Sodeif Ahadpour

correlation which can be achieved for a quantum system based on oscillating molecules [22]. Investigating the coupling between different vibrational modes in molecular systems plays important roles in quantum computation [10, 11]. So anyone can ask whether real quantum properties such as entanglement can perform a vast function in biology. If the production of entanglement is guaranteed in biological systems can provide t
