Astronomers have used a high-energy burst of light from a distant galaxy to test the fabric of space and time. The work is the best test yet of attempts to create a 'theory of everything'. More Articles

Scientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically – but has up to five levels of energy instead of the usual two. The findings are published in the August 7 issue of Science.

What is time? No, really, what is it? A dimension of space-time, says relativity, but is it physical? Or just mental? Why does it seem to move forward and not back? Does the universe acknowledge the arrow of time that we experience? How big is time? Does our notion of "now" h …

With all the talk about Moore's Law, and doomsday predictions of the industry hitting the ceiling of what's possible with regular transistors, you'd almost forget that a lot of people are already thinking about the next revolution in computing: quantum computers.

The computers of tomorrow could be quantum not classical, using the quantum world's strange properties to vastly increase memory and speed up information processing. But making quantum computing parts from standard kit has proved difficult so far.

The line between the quantum realm and the world of classical mechanics we inhabit has just got a little bit blurrier. Physicists have shown that mechanical vibrations can be entangled, which promises to help along attempts to build quantum computers.

QUANTUM mechanics is remarkably weird: even though it is well understood mathematically and can produce accurate, ultra-precise predictions, nobody really knows what it means.

A MATHEMATICAL technique for studying disorder in quantum systems could improve internet keyword searches. It is able to spot significant patterns in large data sets such as web pages and text documents, and may even be adaptable to genome analysis.

..the universe underwent an unimaginably brief but enormous growth spurt immediately after birth. The baby cosmos ballooned from one billionth of a trillionth of a hydrogen atom's diameter to that of a soccer ball within just 10-35 seconds...

Quantum wierdness? Spooky action at a distance? The nature of the natural world is fuzzy at the quantum level, where things can be in two places at the same time. Particles can interact instantaneously over seemingly any distance.

In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experim …

When you hear the word "planet," do you automatically think of the word's literal definition, or of other words, such as "Earth," "space," "Mars," etc.? Especially when used in sentences, words tend to conjure up similar words automatically.

University of Toronto quantum physicists Jeff Lundeen and Aephraim Steinberg have shown that Hardy's paradox, a proposal that has confounded physicists for over a decade, can be confirmed and ultimately resolved, a task which had seemingly been impossible to perform.

"Loop Quantum Gravity" has been tantalizing physicists since 2003 with the idea that our universe could conceivably have emerged from the collapse of a previous universe. Now the theory is poised to make predictions we can actually test.

Poets have long believed the passage of time to be unavoidable, inexorable and generally melancholic. Quantum mechanics says it is fuzzy, ticking along at minimum intervals within which the notion of time is meaningless.

University of Arizona scientists experimenting with some of the coldest gases in the universe have discovered that when atoms in the gas get cold enough, they can spontaneously spin up into what might be described as quantum mechanical twisters or hurricanes.

Physicists have taken a step closer to realizing long-distance quantum communication, in which a quantum state is transferred from one location to another by becoming entangled with a traveling photon.
