A new material with a split personality -- part superconductor, part metal -- has been observed by a Princeton University-led research team. The discovery may have implications for the development of next-generation electronics that could transform the way information is stored and processed. The new material -- a crystal called a topological superconductor -- has two electronic identities at once. At very low temperatures, the interior of the crystal behaves like a normal superconductor,...

Braided anyons could lead to more robust quantum computing When confined to a 2-dimensional sheet, some exotic particle-like structures known as anyons appear to entwine in ways that could lead to robust quantum computing schemes, according to research appearing in the November 1 issue of the journal Physical Review B. The physicists at Bell Laboratories who performed the research are hopeful the anyons can be induced to follow paths that twist into braids that would be much more resistant to...

In the world of the very small, researchers at Shanxi University in China have announced progress in understanding the single-molecule magnet, which combines the classical macroscale properties of a magnet with the quantum properties of a nanoscale entity. In the Journal of Applied Physics, Hai-Bin Xue and colleagues studied the statistics of how electrons move through a single-molecule magnet to better understand the magnet's inner level structure. Understanding the single-molecule magnet...

Physicists at UC Santa Barbara have succeeded in combining laser light with trapped electrons to detect and control the electrons' fragile quantum state without erasing it. This is an important step toward using quantum physics to expand computing power and to communicate over long distances without the possibility of eavesdropping. The work appears online today at Science Express. The research, led by David Awschalom, professor of physics, electrical and computer engineering, and director of...

An important step "“"“ one that is essential to the ultimate construction of a quantum computer "“"“ was taken for the first time by physicists at UC Santa Barbara. The discovery is published in the current issue of the journal Nature. The research involves the entanglement of three quantum bits of information, or qubits. Before now, entanglement research in the solid state has only been developed with two qubits. The UCSB finding comes from a collaboration of the...

The rules that govern the world of the very small, quantum mechanics, are known for being bizarre. One of the strangest tenets is something called quantum entanglement, in which two or more objects (such as particles of light, called photons) become inextricably linked, so that measuring certain properties of one object reveals information about the other(s), even if they are separated by thousands of miles. Einstein found the consequences of entanglement so unpalatable he famously dubbed it...

Researchers develop key building block needed to make a quantum computer using silicon A team led by engineers and physicists at the University of New South Wales (UNSW) in Sydney, Australia, have developed one of the key building blocks needed to make a quantum computer using silicon: a "single electron reader". Their work was published today in Nature. Quantum computers promise exponential increases in processing speed over today's computers through their use of the "spin", or magnetic...

Entanglement is a fascinating property connecting quantum systems. Albert Einstein called it the "spooky action at a distance". This bizarre coupling can link particles, even if they are located on opposite sides of the galaxy. The strength of their connections is behind the promising quantum computers, the dream machines capable of quick and efficient computations. The team lead by Rainer Blatt at the Institute of Experimental Physics of the University of Innsbruck has been working very...

Ever since audiences heard Goldfinger utter the famous line, "No, Mr. Bond; I expect you to die," as a laser beam inched its way toward James Bond and threatened to cut him in half, lasers have been thought of as white-hot beams of intensely focused energy capable of burning through anything in their path. Now a team of Yale physicists has used lasers for a completely different purpose, employing them to cool molecules down to temperatures near what's known as absolute zero, about -460...

An international research group led by scientists from the University of Bristol has developed a new approach to quantum computing that could soon be used to perform complex calculations that cannot be done by today's computers. Scientists from Bristol's Centre for Quantum Photonics have developed a silicon chip that could be used to perform complex calculations and simulations using quantum particles in the near future. The researchers believe that their device represents a new route to a...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
