Multi layer QKD protocol using correlated photon of dark soliton array in a wavelength router

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.

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.

A simultaneous generation of QKD and QDC via optical memory array for distributed network security
(2010-12-01)

We propose a novel system of a simultaneous generation of continuous variable quantum key distribution (QKD) and quantum dense coding (QDC) via an optical memory array. The optical memory system is formed by using an array waveguide incorporating a nano-ring resonator, whereas the different spatial light modes can be generated and stored within an optical memory unit. The polarized photon is formed and stored within a storing device, i.e. a ring resonator, whereas the different time slot entangled photons can be generated, transmitted and detected by the different subscriber in the distributed networks. By using the optical memory concept, the continuous variable quantum key distribution is provided. Furthermore, the use of quantum dense coding via time division multiplexing paths, i.e. different time slot, is also plausible. The advantage of the proposed system is that the quantum key distribution can provide the network top security with high capacity and safety, which is the large demand of usage in the public networks. © 2009 Elsevier GmbH.

Quantum key distribution using the localized soliton pulses via a wavelength router in the optical network
(2010-01-01)

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. There are two forms of localized soliton pulses proposed. Firstly, the required information is transmitted via the localized temporal soliton pulse. Secondly, the continuous variable quantum key distribution is formed by using the localized spatial soliton pulse via a quantum router and networks, which is formed by using and optical add/drop multiplexer incorporating in the network. The localized soliton pulses are available for add/drop signals to/from the optical network, where the high security and capacity information can be performed. © 2009 Elsevier GmbH.
