Interaction of Subharmonic Light Modes with Three-Level Atom

Merid Tufa, Fesseha Kassahun,
Abstract :
We have considered the interaction of the subharmonic light modes with a three-level atom. We have found that the effect of this interaction is to decrease the quadrature squeezing and the mean photon number of the two-mode cavity light.

 

Ancilla-Garbage and Cost Aware Quantum Ripple Carry Adder Design in Quantum Computer

Dr Kunal Das,
Abstract :
In quantum computing, reversible logic plays an important role in quantum circuit design as it dissipates less amount of energy in the form of heat. According to Moore’s law, the number of components inside the computing chip will be doubled in eighteen months and the circuit component miniaturization is the reason for huge amount of heat dissipation. In order to overcome this situation Landeur and Bennet have come up with a solution and that is reversible logic circuits. In this paper we have developed 2-qubit,4-qubit and 10-qubit ripple carry adder using QISKit SDK .These are reversible carry adders circuits which will bring back the inputs from any specific combination of outputs. Thereafter, we have analyzed 2-qubit,4-qubit and 10-qubit ripple carry adder made with different quantum gates and as well as our proposed quantum gate and compare all their feasibility from the perspective of Ancilla, Garbage, Number of CNOT,CCNOT gates and Quantum Cost.

 

A Quantum Algorithm for Finding Common Matches Between Databases with Reliable Behavior

Khaled El-Wazan,
Abstract :
Given $\kappa$ databases of unstructured entries, we propose a quantum algorithm to find the common entries between those databases. The proposed algorithm requires $\mathcal{O}(\kappa \sqrt{N})$ queries to find the common entries, where $N$ is the number of records for each database. The proposed algorithm constructs an oracle to mark common entries, and then uses a variation of amplitude amplification technique with reliable behavior to increase the success probability of finding them.

 

Rigid Quantum Secret Sharing Based on Cavity QED Through an Amplitude-Damping Noisy Channel

ELKTTAOUI Abdelghafour,
Abstract :
A proposed model of quantum transmission of a secret message through an amplitude-damping noisy environment via Fock cavity field is achieved. The process is based on the contribution of a cavity QED, to have a rigidity against the eavesdropping attacks. Indeed, the interaction time, the strength coupling and the Fock field number also control the successful probability of the quantum secret sharing, which makes the interception messages more difficult during our proposed model.

 

KP Equation in an unmagnetized warm dusty plasma with grain charge fluctuation for electrostatic waves

Atef Elbendary,
Abstract :
In this work we investigate the propagation of three-dimensional nonlinear dust-acoustic and dust-Coulomb waves in unmagnetized warm dusty plasmas consisting of electrons, ions, and charged dust particles. The grain charge fluctuation is also incorporated through the current balance equation. By using the perturbation method, a Kadomtsev- Petviashvili (KP) equation is obtained. It has been shown that the charge fluctuation would modify the wave structures and waves in those systems are unstable to the high-order long-wave perturbations.

 

Solar Energy Potential and Future Energy of India On Overview

Sumit Kumar Singh,
Abstract :
Once time after the oil crisis in 1973, the world has to think about the alternative resource of energy apart from conventional energy resources (coal, gas and petroleum etc.). Solar energy is the most important alternative resource of the world and has a large potential of green energy. India has a huge potential for generating green electricity from the renewable energy sources. To promote the green energy, government of India launching many schemes for the renewable energy resources. The Jawaharlal Nehru National Solar Mission was launched on the 11th January, 2010 by the Prime Minister. The Mission has set the ambitious target of deploying 20,000 MW of grid connected solar power by 2022 is aimed at reducing the cost of solar power generation in the country through (i) long term policy; (ii) large scale deployment goals; (iii) aggressive R&D; and (iv) domestic production of critical raw materials, components and products, as a result to achieve grid tariff parity by 2022. Mission will create an enabling policy background to achieve this objective and make India a global leader in solar energy. This paper provides an overview on solar energy in India. It reviews the current status of solar energy in terms of existing capacity, along with historical trends of solar energy and future potential of different form of solar energy in India.

 

Implementation of the Grover search algorithm with superconducting qubits in a cavity QED

Taoufik SAID, Abdelhaq Chouikh, Mohamed Bennai,
Abstract :
We propose an effective way to implement the Grover quantum search algorithm based on the qubit-qubit interaction. We show how to implement the proposed quantum search algorithm using two-superconducting-qubit in a cavity QED driven by a strong microwave field. In our scheme, the quantum search algorithm can be implemented in a time of nanosecond-scale which is much shorter than decoherence time and dephasing time, both being the time of microsecond-scale. Numerical simulation under the influence of the Grover algorithm shows that our proposal is realizable with high fidelity. Moreover, we generalize our Implementation of twoqubit Grover search to the case of multi-qubits Grover search. Thus, the scheme might be experimentally achieved efficiently with presently available techniques.
