The strongest scientific evidence for D-Wave's claim to have built commercial quantum computers just got weaker. A new paper finds that classical computing can explain the performance patterns of D-Wave's machines just as well as quantum ...

On a pound-per-pound basis, carbon nanotube-based fibers invented at Rice University have greater capacity to carry electrical current than copper cables of the same mass, according to new research. While individual nanotubes are ...
Scientists at the US Naval Research Laboratory (NRL) have suggested a method that could significantly increase the efficiency of green-blue-ultraviolet LEDs based on GaInN/GaN, AlGaN/GaN and AlInN/GaN quantum wells. It is reckoned that ...
NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet—the longest of any object in the Milky Way galaxy—of high-energy particles. The pulsar, a ...

More than 99.9% of the mass of any atom is concentrated into a quadrillionth of its volume, the part occupied by the nucleus. Unimaginably small, dense and energetic, atomic nuclei are governed by laws quite distinct from those that ...

Why does a mouse's heart beat about the same number of times in its lifetime as an elephant's, although the mouse lives about a year, while an elephant sees 70 winters come and go? Why do small plants and animals mature faster than large ...

Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature – a property ...
A team of physicists is challenging the very limits of Heisenberg's famous uncertainty principle by measuring quantum particles with unprecedented accuracy. Physicists from The University of Queensland have performed joint measurements on ...
Epiwafer foundry and substrate maker IQE plc of Cardiff, Wales, UK says that its laser epiwafer technology has been employed to develop ultra-high-efficiency optical interconnects, as reported in two technical papers presented by Germany's ...

Diamonds may be a girl's best friend,but they could also one day help us understand how the brain processes information,thanks to a new sensing technique developed at MIT. A team in MIT's Quantum Engineering Group has developed a new ...
Nanotechnology is a thriving science. Parts for computers for example are becoming smaller and more precise by the minute. One of the most efficient computers would be the so-called quantum computer. Up to now, its existence has been merely ...
