Abstract: (1659 Views)
The long-distance entanglement distribution is an important issue in quantum information processing. Our aim in this paper is to design a new protocol of quantum repeater by superconducting qubits to distribute entanglement between two superconducting qubits which are far from each other. So, we consider four pairs of entangled qubits where . Entanglement between each adjacent separable qubits (1,4) and (5,8) is created by performing interactions in the presence of an external magnetic field between the separable superconducting qubits (2,3) and (6,7) and operating proper measurement. Finally, the entanglement is distributed between two target qubits (1,8) by performing interaction between qubits (4,5) and operating proper quantum measurements. The entanglement is considered via concurrence and the success probability of the distributed entangled states is calculated. The behavior of the above two-mentioned parameters is periodic, however, they possess acceptable and satisfactory values.
