A Strange Computer Promises Great Speed
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.

WASHINGTON — The Pentagon on Thursday held a successful test flight of a flying bomb that travels faster than the speed of sound and will give military planners the ability to strike targets anywhere in the world in less than a hour.
Launched by rocket from Hawaii at 1130 GMT, the “Advanced Hypersonic Weapon,” or AHW, glided through the upper atmosphere over the Pacific “at hypersonic speed” before hitting its target on the Kwajalein atoll in the Marshall Islands, a Pentagon statement said.
Kwajalein is about 2,500 miles (4,000 kilometers) southwest of Hawaii. The Pentagon did not say what top speeds were reached by the vehicle, which unlike a ballistic missile is maneuverable.
Scientists classify hypersonic speeds as those that exceed Mach 5 — or five times the speed of sound — 3,728 miles (6,000 kilometers) an hour. …

History lessons are useful, and when events are in flux it is the past that can shed light on what the future might hold.
Autocracies, as I have indicated in recent columns, have shelf life. But there are caveats in any generalization, and the shelf life of any particular autocracy could get extended beyond its expiry date.
The current crisis in Egypt erupted with surprising speed for President Hosni Mubarak. The public demonstrations demanding an end to his 30-year rule has undermined him and very likely, as he has himself indicated, will end his presidency. …
