Quantum Computer

The first complete 'quantum computer'
Ion trap Sustained quantum information processing on a chip
For decades physicists have dreamed of building a quantum computer that could solve certain problems faster than a conventional counterpart. Actually building such a thing has proven extremely difficult, but in August Jonathan Home and colleagues at NIST unveiled the first small-scale device that could be described as a "quantum computer". The chip can perform a complete set of quantum logic operations without significant amounts of information being lost in transit.
Over the past few years, Home's team has used ultracold ions to demonstrate separately all of the steps needed for quantum computation. But in 2009, the group made the crucial breakthrough of combining all these stages on a single device, which was, in our view, such a significant piece of work that we felt compelled to pick it as our "breakthrough of the year".
The device even looks a bit like an early computer chip – but don't expect it to be running a quantum version of Windows any time soon. Its overall accuracy of 94% is impressive for a quantum device, but this must be boosted to 99.99% before it could be used in a large-scale quantum computer comprising many such processors.
What do the quantum computing experts have to say? "A great step forward and most impressive," said Hans Bachor, at the Australian National University. "A tour-de-force," said Boris Blinov of the University of Washington.
Home was back in the news in November, when he teamed up with David Hanneke and others at NIST to create a quantum computer from two trapped ions. The device can perform at least 160 different quantum-computing operations.
Much more work must be done before quantum computers become a commercial reality – but real progress was made in 2009.

Internationalized domain name Research at CDAC
An awareness raising national workshop on IDNs for Indian languages was organized on February 10, 2010 at New Delhi by the Centre for Development of Advanced Computing (C-DAC), under the aegis of Department of IT, Ministry of Communications and IT.What is Internationalized domain name? An internationalized domain name (IDN) is an Internet domain name which contains at least one label in the software application (such as browsers) containing a language specific alphabets. Internationalized domain names are stored in the Domain Name System as ASCII (American Standard Code for Information Interchange ) strings.
Internationalized domain name & CDAC: To ensure that India and Indian languages have their rightful place in this age of Information Technology (IT) with the entire Globe being integrated into a web-linked village with the knowledge as the sole differentiator, development of convivial Access Technology , CDAC GIST (Graphics and Intelligence based Script Technology) undertook research and study of various IDN related RFCs and their applicability vis-à-vis Indian Languages.Objectives:
1. Primarily to ensure that a user can create and access URL’s in his own language and
2. Closely associated with the above, to ensure that the average user who is little aware of spoofing or phishing or pharming does not suffer financial loss or identity loss.
3. Thus an average user doesn't care about a seemingly trivial URL string unless he comes across it inadvertently and gets robbed. For him, वीत्त.भारत and.वीत.भारत look the same.
4. By clicking on the worng URL, (s)he could be phished or pharmed.
To prevent such spoofing and phishing attacks in IL scenario, a careful study of some scripts is done by CDAC GIST, especially in the area of homographs: characters and their combinations which look alike but are different in reality, as in the example given above..The research is focused on Domain Names in Indian languages for Hindi, Gujarati, Oriya, Urdu, Gurumukhi etc. and includes the following :NamePrep and StringPrep Profile - RFC-3492PunyCode: Bootstring encoding - RFC-3454Variant tables accompanied by the normalization tables were prepared which would help reducing vulnerability of an IDN against homograph attacks.A single all script font (on the line of Sakal Bharati font) is also developed. In this font a special care of code-point wise different but visually similar characters is taken to help them being distinguished visually in the address bar of a browser.
National Intelligence Grid (NATGRID)
Government of India is setting up a national intelligence grid called NATGRID.It is a brainchild of Home Minister P Chidambaram. This NATGRID will be fully set up by May 2011 where each individual's data ranging from land records, Internet logs, phone records, gun records, driving license, property records, insurance, and income tax records would be available in real time and with no oversight.
NATGRID & UID:
The government believes that UID project may not be enough to eliminate the risks of terror on the domestic front. NATGRID is currently awaiting the approval of the Cabinet Committee on Security.With a UID from the Unique Identification Authority of India being given to every Indian from February 2011, the government would be able track people in real time. A national population registry of all citizens will be established by the 2011 census, during which fingerprints and iris scans would be taken along with GPS records of each household.Basic Idea: The basic idea of the government is to network 21 available databases across government and private agencies to 'flag potential terrorist threats.
How it will work?
These databases will be linked to enable security and intelligence agencies get any information at the press of a button under the National Intelligence Grid. Only 11 selected government agencies will be able to access the grid and a special mechanism will prevent any leakage of data. As such, the raw data will reside with the provider agencies and will be readily available to NATGRID, as it will only take abstracted and approved subsets of information from the original databases.The eleven agencies who will have access to the database include the Intelligence Bureau, Research and Analysis Wing (RAW), Military Intelligence, Revenue Intelligence, National Intelligence Agency and National Security Council. Personnel from these agencies will be work with NATGRID to liaison with their parent organisations and guide them in usage of the data generated.The new system is being designed to help the government agencies combat terror and threats to internal security by generating "actionable" intelligence through search and retrieval from the networked databases. The grid will have a command centre that will double up as an anti-terror hot line and will have an international connect to network with data available in other countries that is useful to keep a tab on suspects.Who is Captain Raghu Raman: In 2009 Mahindra Special Services Group CEO Captain Raghu Raman had been appointed Chief Executive Officer of the National Intelligence Grid (NATGRID) project to strengthen the intelligence sharing and analysing mechanism in the country.He has been hired on a 18 month contract and enjoys the perks of a joint secretary.Captain Raghu Raman is a Former Soldier and during his 10 year stint with the forces he spent time battling counter-insurgency in Punjab, leading troops in active operations in Siachen Glacier, as a UN Peace Keeper in Angola and finally as an instructor teaching tactics and leadership to young officers in the School of Armored Warfare
Action Plan to Enhance Forestry Science
Action Plan to Enhance Forestry Science addresses the issues regarding upgrading the scientific capabilities of India’s forestry establishment include the establishment of the following:
· Forestry Fellowship Programme which will recognise outstanding contributions to forestry sciences, a forestry fellowship programme is being introduced.
· National Forestry Knowledge Forum: A platform where expert knowledge in various issues in forestry will be shared is being developed. This forum will facilitate virtual interactions of experts in forestry. It will be physically located in Delhi and will be open for national and international experts in the field of forestry science.
· National Forestry Information Network: A network is being established with a robust foundation using remote sensing, GIS and MIS. All land based forestry interventions will be geo-mapped and monitored on a time scale, and will be put in the public domain. The process is being guided by a core group of forestry professionals.
· IT for fire monitoring: A programme to use satellite data for early transmission of fire signals to the mobile phones/ PDA’s of field officers is being undertaken. The University of Maryland has agreed to share all active fire data obtained from TERRA and AQUA satellites of NASA every six hours for this. This will not only help in quick fire detection and reducing the response time, but has also helped in identifying fire sensitive areas. This was originally conceived by the MP forest department, which a national e-Governance Award for the initiative.
· National Bureau for Forest Germplasm: A Forest Genetics Resource network is being established along the lines of the Plant Genetics Resource Bureau. The objective would be to identify, characterise, preserve the valuable germplasm of a wide number of forestry species in the country. This will protect our valuable genetic resource against extinction and exploitation.

Update on Polavaram Project
Polavaram Project is located in East Godavari District of Andhra Pradesh. There is a proposal of Government of India to accord national status to Polavaram project.The project will be the first National Project in South India, if it gets the national status.
Please note that beloved Former Chief Minister Y.S. Rajasekhara Reddy laid foundation stone for the project during 2005, with an intention to complete the project within five years.
Recently the country also came up with a new demand to name this project as Indira-YSR Sagar Project. A high-level Central team comprising officials of Water Resources, Central Water and Planning Commission etc. had visited the project site in May 2009. Now, On February 12, 2010 , Union Minister of State for Defence M M Pallamraju says that Centre's nod to Polavaram declaring it as a National project is expected very soon as almost all the hurdles had been removed and the central leaders were convinced of the importance and the benefits from the project.This project will bring in 7.2 lakh acres under assured irrigation besides stabilizing the existing ayacut. It would generate 960 Megawatts of power and supply 24 TMC of water to Visakhapatnam city. The project would be of great benefit for Rayalaseema and Telangana regions also.

NANOWIRE

A nanowire is a nanostructure, with the diameter of the order of a nanometer (10−9 meters). Alternatively, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. At these scales, quantum mechanical effects are important — which coined the term "quantum wires". Many different types of nanowires exist, including metallic (e.g., Ni, Pt, Au), semiconducting (e.g., Si, InP, GaN, etc.), and insulating (e.g., SiO2, TiO2). Molecular nanowires are composed of repeating molecular units either organic (e.g. DNA) or inorganic (e.g. Mo6S9-xIx).
The nanowires could be used, in the near future, to link tiny components into extremely small circuits. Using nanotechnology, such components could be created out of chemical compounds.

Uses of Nanowire

Nanowires still belong to the experimental world of laboratories. However, they may complement or replace carbon nanotubes in some applications. Some early experiments have shown how they can be used to build the next generation of computing devices.
To create active electronic elements, the first key step was to chemically dope a semiconductor nanowire. This has already been done to individual nanowires to create p-type and n-type semiconductors.
The next step was to find a way to create a p-n junction, one of the simplest electronic devices. This was achieved in two ways. The first way was to physically cross a p-type wire over an n-type wire. The second method involved chemically doping a single wire with different dopants along the length. This method created a p-n junction with only one wire.
After p-n junctions were built with nanowires, the next logical step was to build logic gates. By connecting several p-n junctions together, researchers have been able to create the basis of all logic circuits: the AND, OR, and NOT gates have all been built from semiconductor nanowire crossings.
It is possible that semiconductor nanowire crossings will be important to the future of digital computing. Though there are other uses for nanowires beyond these, the only ones that actually take advantage of physics in the nanometer regime are electronic.
Nanowires are being studied for use as photon ballistic waveguides as interconnects in quantum dot/quantum effect well photon logic arrays. Photons travel inside the tube, electrons travel on the outside shell.
When two nanowires acting as photon waveguides cross each other the juncture acts as a quantum dot.
Conducting nanowires offer the possibility of connecting molecular-scale entities in a molecular computer. Dispersions of conducting nanowires in different polymers are being investigated for use as transparent electrodes for flexible flat-screen displays.
Because of their high Young's moduli, their use in mechanically enhancing composites is being investigated. Because nanowires appear in bundles, they may be used as tribological additives to improve friction characteristics and reliability of electronic transducers and actuators.
Because of their high aspect ratio, nanowires are also uniquely suited to dielectrophoretic manipulation.[4]

Unique Identification Project

Unique Identification Project
==========================

This is the step taken by Union goverment to give unique identity proofs to residents of India. This identity will have basic information of the residents of india. When the resident enrolls, basic information of will be collected and will be give a number( not a card). However, this number will not have any intelligence/sensitive information,thus avoids any identity thefts.



BENEFITs
=========
(1) Obtaining the address proofs for Driving License,passports etc will be easy
(2)This will help in improving the delivery of Cental and state flagship program. As lack of identity proof results in harrassement and some case denial of services
(3)It will save Gov. Exchequer by avoiding leakages in Govt programmes.

This is to be noted that one such programme has already been introduced by Election Commission in 1993 and planned to provide Photo Identity card to voters. This programme resulted large burden on Government cosidering the population of india.
This is right step taken from Goverment to give unique no,s which has multiple benefits.But the programme needs to be executed professionally and in phased manner.

Globalisation and Growing Inequality
====================================
World is going through its severe economic downturn since the great economic downturn of 1930's. The ILO report says that the root of this crisis lies in 1990's economic reforms. Throgh this reforms, the world economic order took a turn and headed for different direction and is the main reason for contemporary economic inquality, social security concerns and labour relations.

Recent report of ILO clearly highlights the growing inequality among different section of workers and decrease in the unemployment after the globalization. - Main reason is due to the extinctions of many domestic industries which are affected by the global factors.

Although the 1990s economic reforms were accompanied by “substantial economic development across most regions" there were variation in labour market performance between and within the countries. Moreover, increase in employment also occurred, alongside a redistribution of income " away from labor"
Statistics indicated the share of wages in National Income declined over the past 2 decades. This means that workers gained very less from the economic growth. The rich poor gap also widened.
Nearly two thirds of the countries experienced an increase in income inequalities. Yet another finding is that this rich poor gap is doing so at increased pace.

Financial Globalization has not lived upto its promises. Another problem that it has eroded the Bargaining power of employees and contributed to decline in wage share over and above any effect resulting from trade integration or sectorial change.

The continuing economic slowdown coupled with rising food prices will accentuate the income inequality and affect the employment opportunities of low income group..
Although in line with the economic thinking since the advent of globalization, the report argues that income inequalities could be a good thing as it rewards work quality, talent, and innovation. It strikes a serious note of caution that “there are instances where income inequality reaches excessive levels, in that it represents a danger to social stability while also going against economic efficiency considerations.”
