Qubits are generated via PANDA ring resonator for optical codec

This paper proposes optical CODEC (code/decode) or quantum cryptograph uses a quantum key distribution (QKD) for information security, from which the improvement of the secret information key rate is developed. The QKD is generated by using the bright soliton pulses within a PANDA ring resonator, which is formed by the add/drop filter. Initially, the bright soliton is generated by a fiber laser and input into the proposed system, where the input bright soliton is controlled by the optical switching, where the required pulse trains can be obtained. The QKD can be formed by using the correlated photon of each pulse by using the polarization device control. In addition, the purposed system is performed by a smaller size, in which the secure information with high capacity of channels can be obtained incorporating the qubits generated by the quantum processor, which can be served the large demand bandwidth with the secure communication applications.
