IBM brings quantum computing to the masses

For the first time, IBM Research has thrown open public access to its new quantum processor via the IBM Cloud. Dubbed IBM Quantum Experience, this will provide users with the ability to experiment with individual quantum bits (qubits), process their own experiments, and run some of their own algorithms directly on IBM's quantum processor.Read More

Intel debuts 6th gen Core processor family at IFA 2015

Intel says there are over 500 million computers in use today that are at least 5 years old, frustrating users with slow wake-up times, the inability to wander away from a wall socket for very long and sluggish overall performance. Today at IFA 2015 in Berlin, the company introduced its new 6th generation Core and Xeon processor families that promise 2.5x faster performance over what was available 5 years ago, 30x better graphics and 3x the battery life.Read More

Dutch firm heats homes for free using cloud server power

You've probably noticed how hot a computer can get if it's doing something taxing, like playing a game, for example. The same thing happens with server farms, but on a larger scale. Dutch startup Nerdalize aims to ditch the usual server farm setup and put internet-connected servers in people's homes, using the excess heat to warm the homes free-of-charge. Read More

Nvidia unveils Tegra K1 mobile chip

A year after introducing the world to the mighty Tegra 4 mobile chip, Nvidia has pulled back the CES curtain on a new member of the Tegra family. The company says that the Tegra K1, which boasts a quad-core CPU and a whopping 192-core GPU, should open the door to next-gen PC-class gaming on hand-held mobile devices.Read More

MIT's 110-core Execution Migration CPU chip moves instructions to the data

A 110-core CPU chip has been developed by computer scientists at the Massachusetts Institute of Technology. The chip is based on a new architecture in which instead of bringing data across the chip to the core that happens to want it, you move the program to the core where the data is stored. In practice, this new architecture reduces the amount of on-chip data exchange tenfold, along with the heat and infrastructure demanded by conventional chip architecture.Read More

Undetectable hardware Trojans could compromise cryptography

Researchers have shown that it is possible to compromise the functioning of a cryptographic chip without changing its physical layout. Based on altering the distribution of dopants in a few components on the chip during fabrication, this method represents a big challenge for cyber-security as it is nearly impossible to detect with any currently practical detection scheme.Read More

Stanford scientists build first carbon nanotube computer

In a technological tour de force, researchers at Stanford University have constructed a one-bit, one-instruction programmable computer on a chip using carbon nanotube-based electronics for all logic elements. Containing 178 carbon nanotube field-effect transistors, the computer is only able to carry out only one instruction, called SUBNEG. However, SUBNEG is Turing-complete, allowing the computer to run, albeit with an extraordinary level of inefficiency, any program, given enough memory, time, and programming ingenuity.Read More
