Quantum Computer

A Strange Computer Promises Great Speed

By

VANCOUVER, British Columbia — Our digital age is all about bits, those precise ones and zeros that are the stuff of modern computer code.

But a powerful new type of computer that is about to be commercially deployed by a major American military contractor is taking computing into the strange, subatomic realm of quantum mechanics. In that infinitesimal neighborhood, common sense logic no longer seems to apply. A one can be a one, or it can be a one and a zero and everything in between — all at the same time.

It sounds preposterous, particularly to those familiar with the yes/no world of conventional computing. But academic researchers and scientists at companies like Microsoft, I.B.M. and Hewlett-Packard have been working to develop quantum computers.

Now, Lockheed Martin — which bought an early version of such a computer from the Canadian company D-Wave Systems two years ago — is confident enough in the technology to upgrade it to commercial scale, becoming the first company to use quantum computing as part of its business.

Speaking truth to power

By: Irfan Husain

AS I was researching this article, reading scores of emails and writing to friends and contacts about the reported threat to Asma Jahangir’s life, something odd happened to my Gmail screen.

Now, whenever I open my email account, a red strip appears at the top with the following announcement from Google: “Warning – We believe state-sponsored attackers may be attempting to compromise your account or computer. Protect yourself now.”

Following the link to security advice, I duly changed my password and switched to Chrome, a Google browser that’s supposed to be more secure. But so far, the problem persists. Any advice from tech-savvy readers would be welcome. I understand Google has recently taken to warning users of such attempts from intelligence agencies to hack into their accounts. ….

Catch me if you can – Pakistan’s army the best business corporation

Pakistan’s answer to the iPad is the PACPAD

By CHRIS BRUMMITT

Catch me if you can … Mohammad Imran holds a locally-made PACPad computer tablet at his electronics store in Rawalpindi, Pakistan.

Inside a high-security air force complex that builds jet fighters and weapons systems, Pakistan’s military is working on the latest addition to its sprawling commercial empire: a homegrown version of the iPad.

It’s a venture that bundles together Pakistani engineering and Chinese hardware, and shines a light on the military’s controversial foothold in the consumer market. Supporters say it will boost the economy as well as a troubled nation’s self-esteem.

It all comes together at an air force base in Kamra in northern Pakistan, where avionics engineers – when they’re not working on defense projects – assemble the PACPAD 1.

“The original is the iPad, the copy is the PACPAD,” said Mohammad Imran, who stocks the product at his small computer and mobile phone shop in a mall in Rawalpindi, a city not far from Kamra and the home of the Pakistani army.

The device runs on Android 2.3, an operating system made by Google and given away for free. At around $US200, it’s less than half the price of Apple or Samsung devices and cheaper than other low-end Chinese tablets on the market, with the bonus of a local, one-year guarantee.

The PAC in the name stands for the Pakistan Aeronautical Complex, where it is made. The PAC also makes an e-reader and small laptop.

Urdu Enters the Digital Age

Computer scientists at the University at Buffalo and at Janya Inc. have developed the first software system that will allow for computational processing of documents in Urdu, Pakistan’s national language and one of the world’s five most-spoken languages.
