Researchers successfully simulate a 64-qubit circuit

Quantum computers are based on the principles of quantum mechanics. Compared with classical bits, qubits can be at the superposition between zero and one, so a quantum computer composed of qubits can calculate and store more ...

Kraken becomes first academic machine to achieve petaflop

The National Institute for Computational Sciences' (NICS's) Cray XT5 supercomputer—Kraken—has been upgraded to become the first academic system to surpass a thousand trillion calculations a second, or one petaflop, a ...

Russia unveils own 'almost Android' system

It seems that Russia's defence ministry has little faith in Google's operating systems: it has just unveiled its own encrypted version that has the remarkably familiar feel of an Android.

Darpa seeks new power dynamic for continuation of Moore's Law

Computational capability is an enabler for nearly every military system.  But computational capability is increasingly limited by power requirements and the constraints on the ability to dissipate heat.  One particular ...

UK plans new cyber force to boost strike ability

Britain's defense secretary says it is recruiting hundreds of experts for a new cyber force designed to protect the nation's vital data—and stage cyberattacks if necessary.

Cooling inspired by sweat

In many of today's electronics, the price we pay for speed comes in the form of heat. As the number of processors on a computer chip increases, so does the amount of heat each chip generates—and there's a greater chance ...
