80 Times More Energy Prototype Superconducting Chips that Will Soon Reach 10 Ghz

Researchers from Yokohama National University in Japan have developed a prototype microprocessor using superconductor devices that are about 80 times more energy-efficient than CMOS semiconductor devices. Computers currently use 10% of global electricity. The adiabatic quantum-flux-parametron (AQFP) is a building block for ultra-low-power, high-performance microprocessors, and other computing hardware for the next generation of data …

Room Temperature Superconductor Under Diamond Anvil Pressures

University of Rochester researchers squeezed carbonaceous sulfur hydride in a diamond anvil and it superconducted at 15 degrees Celsius under 270 gigapascals of pressure. This is about 2.5 million times regular atmospheric pressure. The bottom of the Mariana Trench has 1071 times the pressure of regular atmosphere. The sample were between 25 and 35 microns. …

Superconductoring Alloys Found in Meteorites

Researchers used a highly sensitive technique to examine 16 samples from two different meteorites to find new superconducting alloys. One meteorite formed in the iron core of an asteroid and one flung off a planet’s surface by a collision. Above – Credit: Graeme Churchard/flickr. Samples from the Mundrabilla meteorite, which was found in Australia in …

Uranium Ditelluride Could be Spin Triplet Superconductor and Is a New Wonder Material

Uranium di-telluride could be a wonder material for insanely powerful magnets and it could become the basis of next generation quantum computers. UTe2 might be the long-sought-after spin-triplet superconductor. The reason is very simple. If the spins of the electrons in the Cooper pair have opposite directions and we apply a magnetic field, it will …

New Superconducting States Have Been Discovered

Superconductivity has been shown in monolayer crystals of, for example, molybdenum disulphide or tungsten disulfide that have a thickness of just three atoms. ‘In both monolayers, there is a special type of superconductivity in which an internal magnetic field protects the superconducting state from external magnetic fields,’ Ye explains. Normal superconductivity disappears when a large …

New Superconducting Material Could Make Disruption Resistant Quantum Computers

In the new study, Yufan Li and colleagues found that a ring of β-Bi2Pd already naturally exists between two states in the absence of an external magnetic field. Current can inherently circulate both clockwise and counterclockwise, simultaneously, through a ring of β-Bi2Pd. Above – A visual representation of a qubit, which can exist simultaneously between …

Superconductivity at Near Room Temperature Under Very High Pressure

Superconductivity was achieved at a record high temperature of minus-23 degrees Celsius (minus-9 degrees Fahrenheit)—a jump of about 50 degrees compared to the previous confirmed record. This was done at high pressures that were 1.5 million times more than sea level atmosphere. Researchers at the Max Planck Institute for Chemistry in Germany teamed up with …

Tuning Graphene Superconductivity

A Columbia University-led team has developed a new method to finely tune adjacent layers of graphene—lacy, honeycomb-like sheets of carbon atoms—to induce superconductivity. Above – Applying pressure to twisted bilayer graphene transforms the material from a metal to a superconductor.

Calculations of Room Temperature Superconductors But Requiring High Pressure

Calculations confirm the room-temperature superconductivity found by other authors, and show that it results from a strong e-ph interaction which is rather uniformly spread over electronic and vibrational states of both hydrogen and yttrium sublattices. Under high pressure there should be room temperature superconducting materials that are sodalite-like yttrium hydride clathrates. Arxiv – Superconductivity in …

Superconductors Are Near Room Temperature But UHV Lines are Better for the Grid

It has been over 30 years since the discovery of the first high-temperature superconductor. The first high-temperature superconductor was 30 degrees about absolute zero. There was a flurry of work and the critical temperature reached -135 Celsius (138 Kelvin). The progress on improving the temperature at which the materials could work stalled for decades. There …

European EcoSwing Builds First Full Scale Superconductor Wind Turbine

The European EcoSwing project swapped a compact and lightweight electric superconducting generator for a conventional generator in a 3.6 Megawatt wind turbine. The new generator is 4 meters in diameter, 1.5 meters smaller than a conventional one. It sits inside an 88 meter tall 3.6MW turbine in Thyboron, Denmark. The magnets made from a composite …
