The world of hackers is kind of like the Star Wars universe: There's a light side and a dark side of cracking computers.

At the heart of the European antitrust case against Intel are a series of once-confidential memos that provide a rare glimpse into the intense and at times acrimonious negotiations between the world's biggest chip maker and Hewlett-Packard, the world's biggest computer company.

An anonymous reader writes 'Generating entangled photons in a reliable way is impossible right now, stalling the development of the optical quantum computers that would use entangled photons as quantum bits (qubits). Because entangled photons can only be produced at random — which takes time — the most powerful optical quantum computing device use only 6 qubits. UK and Israeli quantum physicists have designed a blueprint for a 'quantum machine gun' that fires out barrages of entangled photons on demand. They think within a few years this device will be built, and could lead to quantum computing using 20 to 30 qubits. Every additional qubit doubles the computing power, so these quantum computers could outperform any existing classical computer, the researchers say. The quantum machine gun is described as 'one of the most exciting theoretical proposals I've read in five years' by a leading quantum physicist.' The research was published in Physical Review Letters earlier this

Intel showed off computer chips and software aimed at a range of mobile devices at its annual developer conference in San Francisco this week.
