“…So it can be said in other words that the flow of encoded information from the system to the environment in the two-qubit teleportation scenario based on Heisenberg's XYZ chain model under atomic dipole and KSEWA interactions is more than the one-qubit teleportation scenario based on this model. These results can be significant in security considerations and information security in quantum communications [34,67,68].…”

“…Quantum teleportation is now recognized as an important method for realizing many quantum protocols, such as measurement-based quantum computing [25], quantum repeaters [26,27], and fallible quantum computing [28]. Experiments were performed first with photons [29] and later with various systems such as trapped ions [30,31], atomic ensembles [32] as well as with high-frequencyphonons [33] and several other systems [34][35][36][37].…”

In this paper, we address the problem of quantum teleportation in single and two-qubit scenarios based on the Heisenberg XYZ two-qubit chain model under the influence of atomic dipole and Kaplan–Shekhtman–Entin–Wohlman–Aharony (KSEWA) interactions. Using the concepts of fidelity threshold and average fidelity in classical and quantum, we reveal the effectiveness of the current channel to remain in the quantum limits. In addition, we investigate the quantum estimation of the encoded phase in single and two-qubit scenarios at the teleportation destination. By using different variables of the system, the average fidelity of the quantum teleportation and the quantum estimation of the encoded phase in one and two teleported qubit(s) can be improved.

“…The application of the teleportation process has been recognized to be quite wide in quantum information theory ranging from satellite-based communication [23][24][25] in the large to teleportation over the chip in the small scales [26][27][28][29][30]. Since the 3-qubit state we intend to teleport has special characteristics as mentioned in [21] (2m + 6) + 3 3 < 3 9…”

In this paper we describe two different probabilistic teleportation protocols for teleporting the same unknown 3-qubit state from the sender Alice to the receiver Bob. The speciality of the state is that it remains a 2-qubit entangled state after any of the three involved qubits is eliminated by partial trace operation. One of the protocols utilizes a two and a three-qubit separate channels while in the other protocol, a five-qubit channel is utilized. One of the channels in the first protocol is a non-maximally entangled Bell state while the 5-qubit channel used in the case of the second protocol is non-maximally entangled. Both the teleportation schemes are probabilistic with the feature that in the case of failure of the teleportation, the state to be teleported is not lost to the sender. So the process can be repeated after failure till success is achieved. Moreover, one of the channels is recovered in the failure case. Both protocols are resumable in the above sense. The above is the speciality of the present work. We analyze the efficiency of our protocol which shows that the present two protocols are better performing than some existing ones.

“…Recently, a group of scientists demonstrated long-distance quantum teleportation from a photonic qubit (quantum bit) at telecom wavelength to a matter qubit, stored as a collective excitation in a solid-state quantum memory [11]. Researchers used an active feed-forward scheme to implement a conditional phase shift on the retrieved qubit, as required by the teleportation protocol.…”

Quantum teleportation is a fascinating phenomenon that has garnered significant attention in the field of physics. Recent research suggest that quantum teleportation may extend beyond the realm of fundamental particles and apply to complex biological systems. In this review article, the phenomenon of quantum teleportation of epigenetic information in plants and its potential implications for the transfer of genome-stored experience to close relatives is explored. The article begins by providing an introduction to the concept of quantum teleportation and its underlying principles. Then, the emerging field of epigenetics is delved into, discussing the role of epigenetic modifications in plant adaptation and response to environmental stimuli. Subsequently, the existing evidence for the transfer of epigenetic information between plants through horizontal gene transfer is presented, along with the exploration of the possibility of quantum teleportation as an alternative mechanism for such transfers. The implications of quantum teleportation for the transfer of genome-stored experience are discussed, including the potential impact on plant evolution and adaptation. Furthermore, the challenges and limitations in studying quantum phenomena in biological systems are addressed, and future directions for research in this exciting field are proposed. In conclusion, while the phenomenon of quantum teleportation of epigenetic information in plants holds promise, further investigation is required to fully understand its mechanisms and implications. This knowledge will provide insights into the feasibility and mechanisms of quantum teleportation in plants.
