Superconducting Chips To Become Reality

May 29, 2009

Superconducting germanium doped by gallium has been produced by scientists at the Forschungszentrum Dresden-Rossendorf (FZD) research center.

Germanium as a new material for chips would enable both faster processes and further miniaturization in micro- and nanoelectronics.

Superconducting disc locked in upside-down levitation

levitation

A dramatic demonstration by physicist Boaz Almog from Tel Aviv University earlier this week illustrates how a superconducting plate can levitate above a track of permanent magnets, New Scientist TV reports.

Superconducting junctions eyed for quantum computing

November 24, 2002

Josephson junctions, a superconducting type of transistor, are being investigated as a possible route to scalable quantum computers by a physicist at the University of Michigan.

Superconducting memory flip-flops in an instant

April 21, 2006

An exotic form of electronic memory made using superconductors could someday be used to make computers that work at unprecedented speeds, say researchers.

Superconducting nanotubes

October 4, 2002

Researchers have discovered a way to convert nanotubes into superconductors by placing hydrogen on the exterior, leading to dense concentrations of charge-carrying electrons.

Carbon nanotubes are considered to be building blocks of future electronic and mechanical devices.

Superconducting nanowire devices could run and run

July 18, 2005

Researchers at Delft University of Technology and Philips Research Laboratories have combined semiconductor nanowires with superconducting contacts to make superconducting transistors. At temperatures below 1 K, the contacts induced superconductivity in the nanowires through the proximity effect.

Superconducting quantum integrated circuit may lead to future quantum computational architecture

An important milestone toward the realization of a large-scale quantum computer, and further demonstration of a new level of the quantum control of light, were accomplished by a team of scientists at UC Santa Barbara and in China and Japan.

The study, published in the Feb. 7 issue of the journal Physical Review Letters, involved scientists from Zhejiang University, China, and NEC Corporation, Japan. The experimental effort was pursued… read more

Superconductivity Rekindles

October 21, 2008

Recent discovery of new high-temperature superconductors has revitalized the search for practical materials by numerous researchers.

Superconductors get a boost from pressure

May 20, 2008

Scientists have found that the superconducting state in so-called “high temperature” superconductors can be induced by high pressure as well as low temperature.

Superconductors can carry over 150 times more electricity than copper wires because they don’t restrict electron movement. But currently, materials have to be cooled below around minus 216 degrees F, which makes them impractical for widespread use.

Superconductors inspire quantum test for dark energy

April 3, 2007

Quantum mechanics says that the vacuum of space is seething with virtual photons that are popping in and out of existence. Physicists suggest that when these virtual photons have a frequency below around 2 terahertz, they are able to interact gravitationally, contributing to dark energy.

Physicist Paul Warburton at University College London is building such a dark energy detector and could have results next year.

Superconductors, Quantum Mechanics and Nanotech to the Rescue

February 11, 2004

A trio of high technologies — superconductors, quantum mechanics and nanotech — may allow cancer specialists to spot tumors so small they elude today’s best imaging methods.

A “Superconducting QUantum Interference Device,” or SQUID, lets oncologists and surgeons locate previously injected tumor-specific nanoparticles that act like submicroscopic cancer-detection beacons.

Superefficient Solar from Nanotubes

September 15, 2009

The carbon nanotube at center is connected to several electrodes and acts as a superefficient photovoltaic cell by converting energy from photons into electron movement instead of heat (AAAS/Science)

A photovoltaic cell made from a single carbon nanotube that can take advantage of more of the energy in light than conventional photovoltaics has been created by Cornell University researchers.

Superflies bred to be the first astronauts on Titan

Drosophila titanus

Artist Andy Gracie is attempting to breed a strain of fruit fly that could survive on Titan, Saturn’s largest moon, New Scientist CultureLab reports.

The first stage of his work, “The Quest for Drosophila Titanus,” is part of an exhibition currently touring the UK.

The purpose? “In about three to four billion years, the Sun will expand so much that Earth will become uninhabitable, but perhaps… read more

Superhumans Possible Via Designer Cloning

April 21, 2008

A recently developed technique that might eventually produce facsimiles of human embryonic stem cells from skin cells opens a whole new can of worms–the possibility of creating chimera humans, Robert Lanza, chief scientific officer of Advanced Cell Technology, says.

“If we had a few skin cells from Albert Einstein, or anyone else in the world, you could have a child that is say 10 per cent or 70 per… read more

Superintelligence reading group

superintelligence

Nick Bostrom’s eagerly awaited Superintelligence is due to be published in the U.S. this week, and MIRI will be running an online reading group where you can join with others to ask questions, discuss ideas, and probe the arguments more deeply, according to MIRI research assistant Katja Grace.

As Oxford University Press notes, “Superintelligence asks the questions: What happens when machines surpass humans in general intelligence? Will artificial… read more
