Speed limits for quantum gates in multi-qubit systems

We use analytical and numerical calculations to obtain speed limits for various unitary quantum operations in multiqubit systems under typical experimental conditions. The operations that we consider include single-, two-, and three-qubit gates, as well as quantum-state transfer in a chain of qubits. We find in particular that simple methods for implementing two-qubit gates generally provide the fastest possible implementations of these gates. We also find that the three-qubit Toffoli gate time varies greatly depending on the type of interactions and the system's geometry, taking only slightly longer than a two-qubit controlled-NOT (CNOT) gate for a triangle geometry. The speed limit for quantum-state transfer across a qubit chain is set by the maximum spin-wave speed in the chain.Comment: 7 pages (two-column), 2 figures, 2 table

A short proof of the G\"ottsche conjecture

We prove that for a sufficiently ample line bundle $L$ on a surface $S$, the number of $\delta$-nodal curves in a general $\delta$-dimensional linear system is given by a universal polynomial of degree $\delta$ in the four numbers $L^2,\,L.K_S,\,K_S^2$ and $c_2(S)$. The technique is a study of Hilbert schemes of points on curves on a surface, using the BPS calculus of [PT3] and the computation of tautological integrals on Hilbert schemes by Ellingsrud, G\"ottsche and Lehn. We are also able to weaken the ampleness required, from G\"ottsche's $(5\delta-1)$-very ample to $\delta$-very ample.Comment: 8 pages. Published versio

Quantum algorithm for simulating the dynamics of an open quantum system

In the study of open quantum systems, one typically obtains the decoherence dynamics by solving a master equation. The master equation is derived using knowledge of some basic properties of the system, the environment and their interaction: one basically needs to know the operators through which the system couples to the environment and the spectral density of the environment. For a large system, it could become prohibitively difficult to even write down the appropriate master equation, let alone solve it on a classical computer. In this paper, we present a quantum algorithm for simulating the dynamics of an open quantum system. On a quantum computer, the environment can be simulated using ancilla qubits with properly chosen single-qubit frequencies and with properly designed coupling to the system qubits. The parameters used in the simulation are easily derived from the parameters of the system+environment Hamiltonian. The algorithm is designed to simulate Markovian dynamics, but it can also be used to simulate non-Markovian dynamics provided that this dynamics can be obtained by embedding the system of interest into a larger system that obeys Markovian dynamics. We estimate the resource requirements for the algorithm. In particular, we show that for sufficiently slow decoherence a single ancilla qubit could be sufficient to represent the entire environment, in principle.Comment: 5 figures, two table

STUDY OF CORPORATE SOCIAL RESPONSIBILITY (CSR) VISION AND POLICY (with special reference to Reliance Industries Ltd.)

The impact of corporate social responsibility (CSR) ratings has grown exponentially in the last decade.  Nevertheless,  there  remains  a  extended  debate  about  the  acceptability  and  value of corporate responses to CSR concerns. There are different views of the role of the firm  in  society  and disagreement  as  to  whether  wealth  maximization  should  be  the  sole  goal  of  a  corporation.    An  increasing  number  of  shareholders,  analysts,  regulators,  activists,  labor  unions, employees,  community  organizations,  and  news  media  are  asking  companies  to  be  accountable  for  an  ever-changing  set  of  CSR  issues.  There is increasing demand for transparency   and   growing   expectations   that   corporations   measure,   report,   and   continuously improve their social, environmental, and economic performance.  Reliance Industries Limited (RIL) is India's largest private sector enterprise withBusinesses across the energy and materials value chain and a strong presence in the rapidly expanding retail, telecommunications and media sectors.This study depicts to RIL's diverse projects and operations touch lives of people in many ways and create value by helping in overall and holistic development of communities across multiple geographies. Through its various initiatives, the group endeavors to play a relevant role by serving communities and projects that address gaps in basic societal requirements

IMPLEMENTATION OF ENTERPRISE RESOURCE PLANNING (ERP) AT KAKA HALWAI SWEET CENTRE, PUNE - A SMART CITY INITIATIVE

A smart city is an urban development vision to integrate information through Enterprise resource planning (ERP) solutions in a secure fashion to manage a city’s assets – the city’s assets include, but not limited to, local departments information systems, schools, libraries, transportation systems, hospitals, power plants, water supply networks, waste management, law enforcement, and other community services. The goal of building a smart city is to improve quality of life by using technology to improve the efficiency of services and meet residents’ needs.  This paper discusses issues concerning the implementation of Enterprise Resource Planning (ERP) software specifically at Kaka Halwai Sweet Centre, Pune. The paper looks at various examples of implementation and identifies several common traits that are present amongst all successful attempts. For any ERP implementation, a business needs to conduct a thorough analysis of its own core operations. This process helps the company to prioritize areas for improvement as well as determining what the ERP should be used for. A risk assessment is then made surrounding the ERP. If the benefits of implementation outweigh the cost, the next step of the implementation cycles should be preceded. Realistic benchmarks and achievable goals need to be clearly defined and discussed with the management. The progress and budget of the ERP project should be closely monitored. Often failing implementation examples have shown us that project teams lose focus and go off in tangent. It is then management’s responsibility to disregard the sunk costs and assess whether the project should be continue. Lastly, other factors such as post implementation issues and involvement of external parties are the major concern in ERP implementation as an initiative of smart city

DOSE MORTALITY RESPONCES OF BLISTER BEETLES AGAINST SOME INSECTICIDES

In view of significant damage potential of adult blister beetles, dose mortality response for number of insecticides was evaluated to find out efficacious alternative for management of blister beetles. The experiments were conducted at Insect Toxicology Laboratory, Department of Agricutural Entomology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra). The insecticides viz., chlorpyriphos 50 EC + cypermethrin 5 EC (0.1375%), lambda cyhalothrin 2.5 EC (0.00375%), alphamethrin 20 EC (0.05%), cypermethrin 10 EC (0.01%), fenvalerate 20 EC (0.02%) and deltamethrin 2.8 EC (0.0042%) at field dose inflicted 100 per cent mortality, within 24 hours. The data on relative toxicity revealed that lambda cyhalothrin 2.5 EC, deltamethrin 2.8 EC and cypermethrin 10 EC were 188.3, 113.0 and 56.5 times more toxic with reference to chlorpyriphos dust, respectively. The order of toxicity based on LC50 values for insecticides under evaluation was lambda cyhalothrin (0.06 ppm) > deltamethrin (0.1 ppm) > cypermethrin (0.2 ppm) > alphamethrin (0.4 ppm) > fenvalerate (0.6 ppm) > chlorpyriphos + Cypermethrin (0.8 ppm) > methyl parathion dust (1.1 ppm) > fenvalerate dust (3.0 ppm) > chlorpyriphos dust (11.3 ppm). Lower LT50 values at 103 dilutions was recorded in cypermethrin (10.0h) and chorpyriphos + cypermethrin (13.0h). In case of dust formulations, minimum LT50 value was recorded with methyl parathion (83.1h), whereas, fenvalerate dust (109.2h) registered highest value. Similar, efficacy trend based on LT50 values was recorded at 104 dilutions. Synthetic pyrethroids proved efficient in inflicting mortality quickly and at lower dose, thus, suggesting their potential in management of blister beetles

FDI IN RETAIL SECTOR IN INDIA: ITS OPPORTUNITIES AND CHALLENGES

For the economic development of a nation efficient retailing network is crucial one. Retail industry will grow manifold in the next few years and FDI will only give it a boost. Since 2000 government has provided favorable ground for growth of organized retailing in India through its supportive policies. Within a decade the scenario of organised retailing sector has changed taking a flight to 5% and further expected to maintain higher pace. Till now retail growth in India has been achieved primarily due to rising consumerism and initiatives in the private sector. However, while retailing currently remains closed to FDI, this is an area of ongoing debate. The paper describes the Indian Retailing and its present position. The paper further discusses the FDI in single brand retailing and multi Brand Retailing and opportunities, threats and challenges to FDI in Retailing in India

Economic Analysis of Traditional and Sri Method of Paddy Cultivation

The conventional paddy growing tracts are in worst crisis due to social, biological and technical setbacks. Well acclaimed rice bowls in several part of the nation is facing a decline in area, production and productivity. In India, there is a growing demand for rice due to ever escalating population. Rice is consumed both in urban and rural area and its consumption is growing due to high-income elasticity of demand. To meet the growing demand, a rapid income in paddy production is needed. But there is little scope to increase the area; hence increase in production and productivity with an improvement in efficiency of production to act as a technological breakthrough to meet the growing demand
