    We propose a new protocol of the multi layers quantum router generated by using the multiplexed dark soliton pulses within a microring resonator system. Initially, the multi dark solitons are input into a microring system, where the dynamic dark solitons are controlled and the required quantum states generated. The multivariable quantum key distribution can be formed by using the correlated photon pair of each dark soliton center wavelengths, where the quantum keys (codes) are generated and recovered via the quantum processor in the wavelength router. In application, the secure information with high capacity can be performed incorporating the quantum keys via the quantum processor in the multivariable quantum router.

    We propose a new system of quantum cryptography for QKD protocol with privacy amplification for internet security using Gaussian pulse propagating within a nonlinear ring resonator system, quantum processor and a wavelength router. To increase the channel capacity and security, the multiplexer is operated incorporating a quantum processing unit via an optical multiplexer. The transmission part can be used to generate the high capacity quantum codes within the series of micro ring resonators and an add/drop filter. The receiver part can be communicated by using the quantum key (quantum bit, qubit) via a wavelength router and quantum processors. The reference states can be recognized by using the cloning unit, which is operated by the add/drop filter, where the communication between Alice and Bob can be performed. Results obtained have shown that the correlated photons can be generated and formed the entangled photon pair, which is allowed to form the secret key between Alice and Bob. In application, the embedded system within the computer processing unit is available for quantum computer. © 2010 Published by Elsevier Ltd.
