A quadruple micro PANDA ring resonator quantum gate device is designed and investigated schematically. The simulation results of the optimum propagation of soliton polarized states in the device depend heavily on initial phase angles of the input ports. The quality factor under varying of nonlinear coupling constant of micro strip line waveguides are also analyzed. The simulation results show more robust under the wide range of the outer tunneling frequency in whispering gallery modes of the device. This means that an optical trapping efficiency is attained and get more stable qubit processing.

We firstly present and analyze a feasible schematic optical sensor made from PANDA ring resonator which generates WGM of tunneling photons to be used in the atomic trapping process in quantum computer processing to teleport quantum states. A simulation done by launching electromagnetics of Gaussian soliton pulses into an optical tweezers device is given to obtain time dependent evolution of polarization qubit states. It shows that under very low temperature, an optimum photon resonant frequency of such qubit has sufficient stability lifetime to be used in quantum signal states transferring purposes.
The aim of this work is about establishing and analyzing the Hamiltonian for entangled photon generation in a micro PANDA ring resonator for a quantum key generation unit in quantum cryptography processing. The reduced density matrix for two level states of qubits is also analyzed by using dynamics Heisenberg equation of motion. The master equation in the thermal effect shows fluctuation of the corresponding c-operators in phase space. The optimum simulation result for probability of qubit states survive for the existence of a surrounding heat bath is also showed and discussed.
Here we present a fully quantum mechanical transfer function model for travelling wave whispering gallery mode resonators. Micro-resonators, such as ring and disk resonators, have been key to the development of high performance chip-scale photonic systems due to their compact footprint, sensitivity and low power operation. In this work we present the first understanding of these resonators to any arbitrary multi-photon state. This was achieved by developing a model that utilizes an efficient scheme for determining the quantum electrodynamic transfer functions relating the Bosonic input/output mode operators in the resonator. This approach has been applied to the understanding of both single photon and two-photon states. In this work we will present a key result on a resonant Hong-Ou-Mandel effect that is inherently realized for any resonator-waveguide coupling constants and can operate over a wide range of resonance conditions. Furthermore, the transfer function approach allows for the straightforward understanding of any resonator-waveguide network with arbitrary modes. This will directly enable the application of quantum resonators to the realization of robust, scalable and efficient Linear Optical Quantum Computing (LOQC) gates. Consequently, it is expected that resonators can be used for both Nonlinear Sign Shift and CNOT gates. And these gates can robustly controlled and efficiently tuned using standard electro-optic effects available in a variety of material systems, such as, Silicon.
Whispering gallery modes (WGMs) of waves in nature such as electromagnetic wave, sound wave, and matter wave have shown interesting results, which can be useful for fundamental studies and applications in optoelectronics and nanoelectronics, especially after the announcement of the 2012 Nobel Prize in Physics for WGMs [1,2], where the authors confirmed that atoms can be trapped (stopped) by using WGMs in a microsphere. However, there are two more kinds of devices that can be used to trap light beams (atoms); the use of microcavity arrays performed by Yanik and Fan [3], and a nonlinear microring resonator by Yupapin and Pornsuwancharoen [4] for stopping light. Recently, Ang and Ngo [5] have also done experiments with slowing light in microresonators using a microring system. In this article, a new design of microring resonator device is proposed, which can be used to generate four forms of light simultaneously on a chip, whereas the storing and harvesting of trapped atoms/molecules can also be available. The proposed device is made up of silica and InGaAsP/InP with linear optical add-drop filter incorporating two nonlinear micro/nano rings on both sides of the center ring (modified add-drop filter). This particular configuration is known as a PANDA ring resonator [6] as shown in Figure 14.1. Light pulse, for instance, Gaussian, and bright and dark solitons are fed into the system through different ports such as an add port and through port. By using the practical device parameters, the simulation results are obtained using the Optiwave and MATLAB programs. Results obtained by both analytical and numerical methods show that many applications can be exploited. In application, when the practical device parameters are used, then such a device can be fabricated and implemented in the near future.
In this letter, a new design of microring resonator device is proposed which can be used to generate four forms of light simultaneously on a chip, while the storing and harvesting of trapped atoms/molecules can also be available. The proposed device is made up of silica and InGaAsP/ InP with linear optical add-drop filter incorporating two nonlinear micro/nano rings on both sides of the center ring (add-drop filter). This particular configuration is known as a “PANDA” ring resonator [7] as shown in figure1. Light pulse, for instance, Gaussian, bright and dark solutions are fed into the system through different ports such as add port and through port. By using the practical device parameters, the simulation results are obtained using the Opt wave and MATLAB programs. Results obtained by both analytical and numerical methods show that many applications can be exploited. In application, when the practical device parameters are used, then such device can be fabricated and implemented in the near future. The proposed system can be used for many applications, especially, when the device is coated by a metallic material [8]. The applications such as atom/molecule transportation, molecule/atom antenna, atomic/ molecular automata, atom/molecule electronic devices, cells/atom distributed sensors, cells/atom radio, cells communications, micro Faraday cage, molecular/atom storage and logistics, atom/molecule trapping (storage) or cooling, everlasting atom/molecule investigation atomic/molecular storage for quantum gate or computer application, storm search and navigator sensors, magnetic/spin networks, magnetic net, micro plasma source, 3-D flat panel device and large cooling area (volume) can be constructed in the same way as a single device. In this work one of them is demonstrate. Under the stopping and storing condition, the system is considered as the storage unit, where atom or molecule can be trapped by the whispering gallery light beam at the center. The whispering gallery mode result is obtained by using the Optiwave program as shown in figure 2. The ring material is InGaAsP/ InP, where the device parameters are given in figure caption. By using the MATLAB program, the whispering gallery modes of four state of light i.e. fast, slow, stopping and storing can be generated and controlled simultaneously on-chip as shown in figure 3. The storing stage can be seen easily, while the stopping condition can be observed and the following conditions satisfied: (i) the center signal is lost in time between fast and slow signals or (ii) there is no movement among trapped particles or molecules i.e. the exchange of angular momentum introduces the conservation of angular momentum, where the combination of scattering and gradient forces is balanced under the adiabatic process.
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.
