    We propose a new technique of signal synchronization using the correlated photon and a quantum processor, which can be performed incorporating in the communication link. The advantage is that data identification can be transmitted associating with the information data, whereas the synchronous key can be provided between Alice and Bob by using the dark solution tail(array) to form the quantum bits(qubits) via the quantum processor. In this paper, the dark soliton array is used to form the multi variable packet switching, which can be used to increase the communication capacity, whereas the security of data can be performed by the secret codes. Moreover, the secret codes can also be used to form the data identification which is known as signal (data) synchronization.

    We propose a novel system of an optical/quantum memory generation, which can be used for multi-optical/quantum memory applications. The large bandwidth of a single pulse is generated using a soliton pulse in a Kerr-type nonlinear medium, i.e. a nonlinear waveguide. The generation of the localized temporal and spatial soliton pulses within the nano-waveguide is achieved. The free spectrum range enhancement of the generated multi-soliton signals can be formed and achieved using the nano-waveguide incorporating the Mach Zhender Interferometer (MZI). The different light path of the soliton pulses is introduced by the delayed lines of the interferometer. This improves the wavelength free spectrum range, where the different entangled photon pairs can also obtained. Furthermore, the generated photons can be filtered and stored within a system, where the storage of single or multi-photons using the proposed system can be achieved, which in turn can be used for multi-optical/quantum memory applications. © 2009 Elsevier GmbH.
