Quantum computers may have higher 'speed limits' than thought

How fast will a quantum computer be able to calculate? While fully functional versions of these long-sought technological marvels have yet to be built, one theorist at the National Institute of Standards and Technology (NIST) ...

Towards new IT devices with stable and transformable solitons

Unavoidably, each digital information we send around the globe is prone to be lost. Travelling long ways in wires, the initial signal decays and scatters by colliding with impurities and neighboring electromagnetic fields. ...

Scientists build a neural network using plastic memristors

A collaborative of Russian and Italian scientists has created a neural network based on polymeric memristors, devices that can potentially be used to build fundamentally new computers. According to the researchers, these ...

Quick-change materials break the silicon speed limit for computers

(Phys.org) —Faster, smaller, greener computers, capable of processing information up to 1,000 times faster than currently available models, could be made possible by replacing silicon with materials that can switch back ...

Calculations with nanoscale smart particles

Researchers from the Institute of General Physics of the Russian Academy of Sciences, the Institute of Bioorganic Chemistry of the Russian Academy of Sciences and MIPT have made an important step towards creating medical ...

Pairing up single atoms in silicon for quantum computing

(Phys.org) —Australian engineers detect in real-time the quantum spin properties of a pair of atoms inside a silicon chip, and disclose new method to perform quantum logic operations between two atoms.

Beyond the Moore's Law: Nanocomputing using nanowire tiles

An interdisciplinary team of scientists and engineers from The MITRE Corporation and Harvard University have taken key steps toward ultra-small electronic computer systems that push beyond the imminent end of Moore's Law, ...

How losing information can benefit quantum computing

Suggesting that quantum computers might benefit from losing some data, physicists at the National Institute of Standards and Technology (NIST) have entangled—linked the quantum properties of—two ions by leaking judiciously ...

Entanglement in a flash (w/ video)

(Phys.org) —JQI researchers under the direction of Chris Monroe have produced quantum entanglement between a single atom's motion and its spin state thousands of times faster than previously reported, demonstrating unprecedented ...
