Intel-backed boffins demo long-lived silicon qubit

Bit by bit, the world gets closer to creating the quantum equivalent of a storage gate – a silicon-based qubit that can last long enough for general-purpose computing. If you want to use the superposition – the quantum property in which a gate can exist as 0 and 1 at the same time – for computation, it needs a usable “ …

Boffins unwrap bargain-basement processor that talks light and current

Christmas is a time of miracles, to paraphrase Hans Gruber, and US researchers claim to have pulled off one in silicon photonics: they say they've mainlined super-fast optic communications into a RISC CPU using cheap, bog-standard manufacturing techniques. Chips using light to shunt data around a processor and to and from its …

Qualcomm sheds last veil from Snapdragon 820

After letting the world in on glimpses of its Snapdragon 820 processor for a few months, Qualcomm has finally taken the lamp out of the basket. The company will have high hopes for the chip: troubles in China, being jilted by Samsung, and talk of overheating in its Snapdragon 810 chips left it with disappointing revenue and …

Au oh, there's gold in them thar server farms, so lead the way

All these servers that we pack into the data centres have a limited life span, they're made of metal, metals even, and scrap metal has a value. So, what's the stuff that's in there and how much is it worth? As metal that is, once it's done its job of pumping the electrons around? Not a lot when you consider what they cost to …

Cool-headed boffins overcome sticky issue: Graphene-based film could turn heat down

A graphene-based film could help to cool down overheating microelectronic devices, scientists have claimed in a new study. Researchers at Chalmers University, led by professor Johan Liu, have developed the 20 micrometre-thick film, which apparently has a thermal conductivity capacity of 1,600 W/mK – four times that of copper …

Cavium adds 4/16 core SoCs

Cavium is filling out a scale gap in its Octeon III system-on-a-chip (SoC) range with he four-to-sixteen core CN72xx and CN73xx variants that are pin-compatible with the rest of the range. The MIPS64-based SoCs are low-power network processors pitched between the one-to-four core CN71xx and the 24-48 CN78xx range. The chips …

Incomprehensible boffins bring quantum computers a step closer

The long-awaited arrival of quantum computers could be one step closer, as boffins from Oz have for the first time encoded quantum information in silicon. Unlike conventional computers, which store data on transistors and hard drives, quantum computers encode data in states of microscopic objects called qubits. The arrival of …

Broadcom targets terabit switch markets with fat StrataDNX chipset

Broadcom wants a bigger footprint in the router and switch market with the next iteration of its top-line silicon, the StrataDNX line. While conceding that merchant silicon isn't going to push Cisco or Juniper Networks out of the network core where the biggest traffic flows exist, Broadcom reckons the ability to support beyond …

Boffins erect semi-hard 3D silicon: Pop-up micro-machines breakthrough

Pic Researchers have found a way to make tiny 3D structures out of silicon that "pop up" into shape when glued to an elastic substrate, paving the way to new forms of electronics. The minute shapes mimic complex mechanisms in biology – such as the internal structure of teeth and networks of veins and brain cells – and could be …

Xpliant targets white-label Ethernet switch vendors with shiny new silicon

Ethernet silicon vendor Xpliant – currently being digested by Cavium in an acquisition due to conclude in 2015 – is hoping to knock Broadcom out of its spot at the heart of the Ethernet switch market. The upstart, launched in 2011, says it'll have sample silicon in Q4 2014 for an architecture designed to combine speed and …

Calxeda co-founder unleashs 48-core ARM SoC

Computex ARM vendor Cavium has revealed 48-core silicon it reckons will pitch it into high-end data centre and server apps. Cavium has hired Larry Wikelius, co-founder of failed ARM server silicon vendor Calxeda, and his former colleague Gopal Hegde (who played a part in creating Cisco's UCS servers). Both are insistent that now is the …

QUANTUM COMPUTER in WORLD RECORD qubit stunner

Researchers have managed to store data in a qubit – a quantum computer's binary bit – and maintain it in a superposition state, where ones and zeros exist simultaneously, for 39 minutes, beating the previous record of just a few seconds. qubit Hot stuff! What an artist reckons a qubit looks like "This opens up the …

Boffins hide supercapacitors on silicon chips

Scientists at Vanderbilt University have created a silicon-based supercapacitor they say could scale all the way from grid-level storage down to consumer electronics. The reason they're trumpeting it as a breakthrough is that silicon, while abundant and with well-established fabrication techniques, doesn't work well in …

Spin doctors brazenly fiddle with tiny bits in front of the neighbours

The University of New South Wales, working with Sandia National Laboratories in New Mexico, is celebrating what it hopes will be another step towards large-scale quantum computing: a technique that can address single electron qubits separated by mere nanometres. Quantum bits - qubits - are the quantum-physics counterpart to …
