How do you build a large-scale quantum computer? Posted: 25 Feb 2014 09:22 AM PST Physicists have now proposed a modular quantum computer architecture that promises scalability to much larger numbers of qubits. The components of this architecture have individually been tested and are available, making it a promising approach.

First contagious airborne WiFi virus discovered Posted: 25 Feb 2014 08:29 AM PST Researchers have shown for the first time that WiFi networks can be infected with a virus that can move through densely populated areas as efficiently as the common cold spreads between humans.

System that automatically fills gaps in computer programmers' code gains power Posted: 25 Feb 2014 07:16 AM PST A system that automatically fills in the gaps in programmers' code becomes more powerful. A recent programming language called Sketch allows programmers to simply omit some of the computational details of their code. Sketch then automatically fills in the gaps.

Using stolen computer processing cycles to mine Bitcoin Posted: 25 Feb 2014 07:15 AM PST Computer scientists have taken an unprecedented, in-depth look at how malware operators use the computers they infect to mine Bitcoin, a virtual currency whose value is highly volatile. Researchers examined more than 2,000 pieces of malware used by Bitcoin mining operations in 2012 and 2013. They were able to estimate how much money operators made off their operations and which countries were most affected.
