Despite quantum's gains, standard computers still rule

PARIS: Quantum computing is getting the headlines these days, with buzz among scientists of giga-powered number-crunching and unbreakable encryption.
The US National Security Agency (NSA) is reportedly advancing towards a quantum computer that could crack almost any conventional algorithm.
The NSA plans were leaked by contractor Edward Snowden and reported by The Washington Post on Thursday.
Details of its work remain sketchy, though. And the agency is only one of many players, both public and corporate, in a field that must overcome many hurdles before it can dethrone standard computing.
Conventional computers work by processing binary code – an information currency that exists in one of two states, either zero or 1.
Quantum computers, though, break free of the two-state constraints.
They harness the principle of quantum mechanics, when strange things occur through the state of an atom’s spin, something called angular momentum.
In a quantum state, the atom goes into a condition called superposition. It can hold the value of zero or 1 or both values at the same time.
This juggling trick holds out the possibility of parallel processing on a massive scale.
An algorithm that a conventional supercomputer might take years to break could be cracked by so-called qubits, or quantum bits, in a fraction of the time.
“The special properties of qubits will allow quantum computers to work on millions of computations at once,” says IBM. “For example, a single 250-qubit state contains more bits of information than there are atoms in the Universe.”
Daunting engineering obstacles have to be overcome, though. In order to achieve the fragile quantum state, a cloud of atoms has to be cooled to near-absolute zero and controlled by pulses of laser.
Changes in temperature, electromagnetic waves and minute defects in material can all wreck the sought-after superposition that fuels the qubit.
Scaling up these computers from hugely expensive, highly protective labs represents “an enormous practical challenge,” the Nobel jury said in 2012, when it awarded that year’s physics prize for fundamental work on the quantum state.
Quantum’s other big plus is a phenomenon called entanglement.
Particles created in a quantum state behave like psychic twins.
Even if they are far apart, a disturbance to one particle affects the other, a phenomenon that Einstein once called “spooky action at a distance.”
Thus if a message sent in a quantum state is intercepted en route, the entanglement is destroyed — and alarm bells ring that someone is eavesdropping.
Achieving quantum cryptography
Entanglement is the big goal of quantum cryptography.
It holds out the possibility of creating a unique, one-time code shared only by sender and recipient that would be almost impossible to decrypt by an outsider. Better still, the message could not even be touched during transmission.
Even without entanglement, though, the quantum state can be useful in cryptography, said Philippe Grangier, a specialist in quantum optics at France’s National Centre for Scientific Research (CNRS).
His team has done tests that sends a standard-encrypted message, along with a quantum-encrypted key, in squirts of light down a fibre-optic cable.
Once received, the key is then used to decode the message.
The technique uses the quantum signature in the key as a burglar alarm, Grangier said in a phone interview.
“Just the slightest interception of the data will reduce the size of the quantum key when it gets to the recipient, and the spy gets detected,” said Grangier.
“The more the spy perseveres, the smaller the key becomes. Eventually, the connection is cut.”
Their greatest length for transmission has been through a cable 80 kilometres (50 miles) long — a distance that is useful for local communications but still way too short for transcontinental use or more.
Going beyond this distance lies the conundrum of how to amplify a weakening light signal down a cable so that the data is repeated but does not lose its quantum state through interference.
Other techniques aim at overcoming the “repeater” problem by line of sight laser transmission, in theory to satellites in near-Earth orbit.

Leading performer: Insurance policy seller becomes globetrotter

After earning the MDRT membership for 13 years in a row, Aswani has now become its life-time member.
KARACHI: 
Teekam Das Aswani did not expect he would frequently be rubbing shoulders with the best of the best in the global life insurance industry when he started selling insurance policies in Hyderabad back in 1999.
With as many as six trips to the United States during the last seven years to meet top achievers in his field belonging to more than 450 companies from 74 countries, Aswani is now a globetrotter in the truest sense of the word.
Founded in 1927, the Million Dollar Round Table (MDRT) – an Illinois-based international association of more than 38,000 insurance professionals – holds a one-of-the-kind, four-day event in North America where approximately 4,000 top performers huddle up to share sales ideas, make presentations, hold networking sessions and listen to motivational speeches every year.
A policy seller has to bring in roughly eight times more business than an average life insurance salesperson to qualify for the basic MDRT membership for a year. To earn membership of the 2014 MDRT – whose annual conference will take place in June in Toronto – a life insurance agent had to generate a premium of Rs3 million in 2013.

In addition to that, life insurance professionals are also encouraged to compete for court of the table/top of the table titles by generating business that is three/six times more than the base MDRT business generation requirement.
After earning the MDRT membership for 13 years in a row, Aswani has now become its life-time member. And why wouldn’t he? Aswani is a pro when it comes to selling insurance.
“Premiums used to be minimal when I joined EFU Life Assurance in 1999. But within two months I was promoted to the position of business development manager,” said Aswani, who now serves as chief business manager.
Premiums were indeed abysmally low at the time Aswani joined the country’s life insurance industry. With less than a decade in operation, private-sector life insurance companies were barely surviving in contrast with the government-owned State Life Insurance Company.
But the tide was turning with private life insurance companies expanding their footprint. Gross premiums of life insurance companies in the private sector have since grown phenomenally, with a compound annualised growth rate of 28.4% between 2006 and 2013 alone.
“As many as 86 people from EFU Life Assurance qualified to become MDRT members in 2013 as opposed to only two in 1999, the year when we started working with the MDRT,” said Mustafa Hussain Oonwala, who is the national sales director of EFU Life Assurance, one of the two largest private-sector life insurance companies operating in Pakistan.
“We’re committed to bearing most MDRT-related expenses for the development of our sales force,” he said.
Should a qualifier decide to become an MDRT member, he must pay a membership fee of $550. In case, he decides to attend the annual conference in North America, he has to pay a registration fee of $675 separately.
According to Oonwala, EFU Life Assurance did not pay any fee initially. Now, it pays the registration fee, but the qualifier must pay the membership fee himself. The company also bears airfare and visa assistance expenses.
Other than EFU Life Assurance, salespeople from conventional and Islamic life insurance companies also take part in the MDRT, albeit without active monetary support from their employers.
Speaking to The Express Tribune, Jubilee Life Insurance CEO Javed Ahmed said his company used to support and actively promote MDRT in the past, but increasing visa restrictions have forced the company to revise its policy.
“Since most of the salespeople do not get US visa to attend the MDRT conference, it eventually becomes a source of de-motivation for the regular qualifiers,” Ahmed said.
Referring to Jubilee Life Insurance’s own version of the MDRT for the company’s top performers called Million Rupee Club, Ahmed said people work hard to be a part of it and have now stopped applying for the MDRT.

PIA to upgrade fleet with 14 new planes by June

The airline will operate two direct flights in a week from Multan – one from Multan-Jeddah every Friday and the other from Multan-Madina every Saturday. PHOTO: FILE
MULTAN: Bringing good news with the start of the new year, Aviation Secretary Muhammad Ali Gardezi has said the fleet of Pakistan International Airlines (PIA) will be upgraded with the addition of 14 new airplanes before June this year.
He was speaking at a ceremony held to mark the launch of direct flights from Multan to Jeddah, Saudi Arabia on Friday. The airline will operate two direct flights in a week from Multan – one from Multan-Jeddah every Friday and the other from Multan-Madina every Saturday.

Four new planes have already arrived while five others, which have been approved by the government, will reach this month. The remaining five will be delivered to PIA by June this year.
Elaborating, Gardezi, who is also the chairman of PIA, said four airplanes had been taken on lease and three more would be acquired on lease of six years.
He pointed out that the major reason behind the losses suffered by the air carrier was the use of airplanes on wrong routes. Before the current management took over, he said, big planes were used on small routes and small planes operated on big routes.
“At present, PIA is earning Rs8 billion a month and our target is Rs15 billion,” he claimed.
Despite losses and high fuel prices, he said, PIA had expanded its network all across the world. “We have started four flights a week to Toronto (Canada) and Kuala Lumpur (Malaysia). More international routes will be introduced.”
Talking about challenges, Gardezi said the biggest challenge the carrier faced was higher fuel prices. “We are paying 56% of our total revenues to cover fuel expenses and only 18% goes for payment of salaries to the employees.”

Discussing the start of flights from Multan to Saudi Arabia, he said a longstanding demand had been met of the residents of Multan, Dera Ghazi Khan, Bahawalpur, Rahim Yar Khan and adjoining areas. With the completion of a new terminal at the Multan Airport, PIA will operate more international flights from there.
He stressed that the PIA management was making efforts to make the carrier a profitable entity by notching up revenues and reducing costs without compromising on service standards.

Gwadar port to open economic portals: Afridi

ISLAMABAD: The Gwadar port project can serve as a key to economic development of the country and drastically improve the lives of the people of Balochistan if its potential is exploited to bolster trade in the region, said Standing Committee Gwadar Promotion and Development Chairman Colonel (Retd) Maqbool Afridi.
The official believed that the natural resources of Africa can be easily shipped to Gwadar and, after value addition, can be reshipped to the global consumer’s markets. “The Gwadar project has the potential to give boost to the present crippled economy of the country in a short span of time,” said Afridi. “Due to its geostrategic location, the Central Asian Republics (CARS) have a short route to world markets and at the same time the developed countries have an easy access to the CARS’ natural resources.”
According to Afridi, the port is well poised to conduct transshipment as well as transit trade, adding that Dubai is earning billions of dollars yearly from transshipment which is 700 km ahead of Gwadar and has to pass through Strait of Hormuz which is a restricted ship movement.

“For transshipment and transit trade there is not a single county which is not dependent on Dubai, Iran, Oman or Pakistan.”   He said Gwadar is a natural deep sea port, different from neighboring ports of Iran and Dubai and has the capacity to have 88 berths and the ability to anchor ships of 1,00,000 to 2,00,000 dead weight tonnage.
“The business and job opportunities created enroute from south (Gwadar) till north (Kunjrab) will benefit all provinces of the country immensely.”

More costly: Pak Suzuki choosing to ride on margins

Pak Suzuki raised prices by 1.5% (or Rs10, 000 to Rs25,000) on different car variants despite 12.23% year on year depreciation in yen against Pak rupee during 2013. PHOTO: FILE
KARACHI: Analyst’s on Friday stated that the decision of Pakistan Suzuki Motors – country’s biggest car maker – to raise car prices on the very first day of 2014 is going to increase its margins but it may dampen its volumetric sales.
This was the first car price hike from any of the three leading car makers in the country. All these car producers raised their prices at different occasions in the previous year.
Pak Suzuki spokesperson said that the company took the step to offset the pressure of rupee depreciation against the dollar and other inflationary effects in recent months.
Meanwhile, InvestCap Research report said that the timing of the price increase was ‘surprising’. “The price increase at this time appears surprising and is expected to improve profitability in the coming year,” read the report. “However, considering the already peaked prices of different variants of the company, the recent price hike may limit gains as volumetric sale of the company may somewhat decline.”
Pak Suzuki raised prices by 1.5% (or Rs10, 000 to Rs25,000) on different car variants despite 12.23% year on year depreciation in yen against Pak rupee during 2013.
“Pak Suzuki must benefit from this price hike, this may have come to offset the effects of electricity prices that the government raised in August 2013,” JS Global Capital analyst Atif Zafar told The Express Tribune.
Analysts say local automobile companies benefitted from the depreciation of yen against rupee in the last three months, which has gained 9% against Yen.
However, dollar appreciation against the rupee during this same period did affect margins of auto companies. For instance, dollar appreciated by 4.7% against rupee and 1.7% yen from October to December 2013.
“The depreciation of rupee and yen against dollar in the fourth quarter of 2013 (October to December) is supposed to be the major factor behind the current rise in cars sale prices,” InvestCap Research report added.
Local car producers received positive news last year when the government reduced the age limit of used car imports from 5 years to 3 years. Due to this decision the imports of used cars gradually dropped in the last 12 months and the sales of locally produced cars increased.
Car importers have demanded the government to reverse this age limit and allow the import of cars at least 5years old in order to increase the competition for local carmakers. However, the local industry maintains that any increase in used car imports will hurt the sales of new cars in the country and hence it is damaging for the industry

The World’s Largest Economies

Emerging economies are smaller than the developed countries - but they are growing faster and opening up, leading to greater investment opportunities than ever before.

There are two methods of GDP calculation: nominal GDP attempts to compare countries using current exchange rates to give an assessment of their clout within the global market. This naturally biases countries with stronger currencies.
Purchasing Power Parity or PPP GDP, on the other hand, tries to take into account that one dollar can buy more in some countries and less in others. It is a better gauge of the internal size of each market.
In the nominal GDP method, we can see that the developed world leads the pack, but that China has already broken into this exclusive club, and is now the second largest economy in the world by both measures.
When we look at PPP GDP, all of the BRIC countries (China, India, Brazil and Russia) are all within the top 10.
Here is the Top 10, as listed by PPP GDP, using 2010 GDP figures:
RankingCountryApproximate GDP- Purchasing Power Parity
1United States of America$14,624,180,000,000 (that is $14.6 trillion dollars if you are trying to count zeros)
2China$10,084,370,000,000
3Japan$4,308,630,000,000
4India$4,001,100,000,000
5Germany$2,932,040,000,000
6Russia$2,218,760,000,000
7Brazil$2,181,680,000,000
8United Kingdom$2,181,070,000,000
9France$2,146,280,000,000
10Italy$1,771,140,000,000
While the US is still the world's dominant economy, and central to the global economic system thanks to the simple fact that the US dollar is the world's reserve currency (ie the currency that we all need in order to trade), we can clearly see that China's clout is rapidly growing. The numbers tell the story not just of the BRIC, but also the G2 or Chamerica, as some are calling the US/ China combo.

FY2013: Telecom sector’s revenues reach all-time high

The sector’s revenues increased by a third, 33.5% to be exact, during the last five years when compared with Rs333.8 billion the industry had grossed in FY09. PHOTO: FILE
KARACHI: 
Telecom sector’s revenues reached an all-time high, increasing by nearly one tenth, as the industry added almost 10 million new cellular connections in the fiscal year 2013, Pakistan Telecommunication Authority revealed in its annual report.
With a major contribution of Rs438 billion or $4.1 billion coming from the five cellular mobile operators (CMOs), telecom sector’s revenues increased to Rs445.7 billion at the end of June 2013, up 9% from Rs409 billion in FY2012.
The sector’s revenues increased by a third, 33.5% to be exact, during the last five years when compared with Rs333.8 billion the industry had grossed in FY09.

The steady growth came on the back of the country’s growing teledensity, which stood at over 75% at the end of FY13, translating to an increase of almost four percentage points over 71.73% in the previous fiscal year. CMOs that cover 71.7% of the population were again the major contributor.
Total number of cellular subscribers increased by 7% to 128.9 million in FY13 when compared with 120 million as of June, 30, 2012 – indicating a steady growth from FY10 to FY13.
When it comes to tax
Telecom is one of the highest tax-paying sectors. The sector, on average, has contributed Rs119 billion a year to the national exchequer between FY09 and FY13. However, its contribution to the national exchequer decreased to Rs124.7 billion during FY13, down by 6.5% from Rs133.4 billion of the last fiscal year.
A breakdown of tax collection showed a 64% year-on-year decrease in PTA’s deposits to the exchequer. The report, however, added that the PTA received Rs6.8 billion from the operators under various regulatory heads and deposited into the nation exchequer till March, 2013.

The investment in the telecom sector saw a significant increase. During FY13, a total of $451 million investment was reported in the sector, which translates to a 47% growth over $240 million in the previous year – CMOs were again the major contributor, investing $421.5 million during the period under review.
With the addition of FY13 telecom investment, the sector was able to attract over $12 billion of investments from FY06 to FY12, according to the report.
The report, however, said the companies reduced their investments in the last two years as they already established most of their networks.
Telecom sector had attracted $6 billion in foreign direct investment (FDI) since FY06 but FY13 ended on a negative note. FDI in telecom sector remained on the negative side of the scale as outflows of $408 million were reported during FY2013.
However, the telecom regulator stated in its report that the FDI outflow could be turned around with auction of mobile spectrum for high-speed internet services, which it expects to complete in the third quarter of FY14.
The report also showed that the imports of telecom equipment including mobile handsets reached almost $1 billion – $918 million to be exact – in FY2013. This, however, was a slight decline from $954 of FY2012, according to PTA’s report.
“The telecom sector continued to grow on a steady pace during FY13 with telecom services, covering 92% of the land area and 75% of the population,” PTA Chairman Syed Ismail Shah was quoted in the
report as saying.
While expressing his vision, the chairman stated he was aiming for an advanced, technology driven, consumer oriented and business friendly environment where fair competition, affordable tariffs, high quality of services and extended land coverage would be the success benchmarks.
