Abstract

In this study, new system of quantum cryptography for network communication is proposed. Multi optical Soliton can be generated and propagate via a nonlinear modified add/drop interferometer system incorporated with a time division multiple access (TDMA) system wherein the transportation of quantum codes is performed. To increase the channel capacity and security of the signals, the PANDA ring resonator is proposed. Chaotic output signals from the PANDA ring resonator are input into the add/drop filter system. Chaotic signals can be filtered by using the add/drop filter system in which multi dark and bright solitons can be obtained and used to generate entangled quantum codes for internet security. In this study soliton pulses with FWHM and FSR of 325 pm and 880 nm are generated, respectively, where the Gaussian pulse with a centre wavelength of 1.55 μm and power of 600 mW is input into the system.

Generation of potential wells used for quantum codes transmission via a TDMA network communication system

Iraj Sadegh Amiri, Mehrnaz Nikmaram, Ali Shahidinejad +1 more

ABSTRACT This paper proposes a technique of quantum code generation using optical tweezers. This technique uses a microring resonator made of nonlinear fibre optics to generate the desired results, which are applicable to Internet security and quantum network cryptography. A modified add/drop interferometer system called PANDA is proposed, which consists of a centred ring resonator connected to smaller ring resonators on the left side. To form the multifunction operations of the PANDA system—for instance, to control, tune and amplify—an additional Gaussian pulse is introduced into the add port of the system. The optical tweezers generated by the dark soliton propagating inside the PANDA ring resonator system are in the form of potential wells. Potential well output can be connected to the quantum signal processing system, which consists of a transmitter and a receiver. The transmitter is used to generate high‐capacity quantum codes within the system, whereas the receiver detects encoded signals known as quantum bits. Therefore, an entangled photon pair can be generated and propagated via an optical communication link such as a time division multiple access system. Here, narrower potential wells with a full‐width half‐maximum of 3.58 and 9.57 nm are generated at the through and drop ports of the PANDA ring resonator system, respectively, where the amplification of the signals occurs during propagation inside the system.

Novel optical cryptography using PANDA ring resonator for highly secured communication

Rattipong Putthacharoen, Pakorn Juleang, Somsak Mitatha +1 more

We propose a novel method of an optical cryptography using the dark-bright soliton conversion control in a modified add/drop optical filter. By using the control arrangement, the obtained outputs of the dynamic states of dark-bright soliton can be used to form the key suppression for communication security application, in which the key recovery can be obtained by controlling the add/drop filter outputs. The optical cryptography consists of an add/drop filter which is used to generate the encryption and decryption keys from the optical keys (LIP signals). A Mach-Zehnder interferometer is used for multiplexing and de-multiplexing operations. Simulation results obtained shows, that the proposed system can be used to form a high security communication system.

Optical-Quantum Security using Dark-Bright Soliton Conversion in a Ring Resonator System

Surachai Tunsiri, Somphone Kanthavong, Louangvilay +2 more

We present a new concept of quantum cryptography using dark-bright soliton conversion behaviors within a nonlinear ring resonator, in which the orthogonal soliton is established among the soliton conversion. A new model of add/drop filters is modified which is known as a PANDA Ring resonator is proposed. The entangled soliton(photon) can work in the same way of the entangled photon, but in this case the entangle soliton is gained more power that give the advantage of long distance quantum communication. In application, the high capacity quantum communication is also variable by using the multivariable entangled solitons.

Two systems consist of microring resonators (MRRs) and an add/drop filter are used to generate signals as localized multi wavelengths. Quantum dense encoding can be performed by output signals of selected wavelengths incorporated to a polarization control system. Therefore dark and bright optical soliton pulses with different time slot are generated. They can be converted into digital logic quantum codes using a decimal convertor system propagating along a wireless networks. Results show that multi soliton wavelength, ranged from 1.55m to 1.56m with FWHM and FSR of 10 pm and 600 pm can be generated respectively.

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.
