    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.

    An atom/molecule/DNA probing and transportation using dynamic optical tweezers via a wavelength router

    A dark soliton pulse beam that has potential applications in the probing and transport of atoms or molecules as an optical tweezers is demonstrated. The trapped pulse beam is formed in the gap between a BP signal at 1500.00 nm and Stokes signal at 1500.09 nm, which has peak powers of -12 dBm. The generated beam is seen to be stable with no fluctuations over a test period of 10 min, which is important to ensure that the transported atom/molecule is not lost in the link media, therefore, the dynamic optical tweezers are now plausible. The theoretical background of the trapped atom/molecule is also analyzed and described in details. The atomic/molecular network via a wavelength router is also described. © 2010 Elsevier GmbH All rights reserved.

    Multi-users quantum key distribution via wavelength routers in an optical network

    We propose a new system of a continuous variable quantum key distribution via a wavelength router in the optical networks. A large bandwidth signal is generated by a soliton pulse propagating within the micro ring resonator, which is allowed to form the continuous wavelength with large tunable channel capacity. Two forms of soliton pulses are generated and localized, i.e. temporal and spatial solitons. The required information can be transmitted via the spatial soliton while the continuous variable quantum key distribution is formed by using the temporal one. This is formed by using an optical add/drop multiplexer incorporated in the optical network, where the localized soliton pulses are available for add/drop signals to/from the optical network. The high security and capacity information can be performed. © 2009 Bentham Science Publishers Ltd.
