"The key question we always ask ourselves is: Who is building this technology and for what purposes?" says Privacy International's Frederike Kaltheuner. "Is it used to help us - or to judge, assess and control us?"

New genre of artificial intelligence programs take computer hacking to another level

SAN FRANCISCO (Reuters) - The nightmare scenario for computer security - artificial intelligence programs that can learn how to evade even the best defenses - may already have arrived. That warning from security researchers is driven home by a team from IBM Corp. (IBM.N) who have used the artificial intelligence technique known as machine learning to build hacking programs that could slip past top-tier defensive measures. The group will unveil details of its experiment at the Black Hat security conference in Las Vegas on Wednesday.

At @defcon hacking conference and just learned how easy it is to physically gain admin access on a voting machine that is used in 18 states. Requires no tools and takes under 2 minutes.

Quantum computers have long been touted as incredibly powerful machines that will be able to solve hugely complex computational problems much faster than any computer we have available today. But no-one can agree on the best way to make them. Who will win the race?

Physicists, engineers and computer scientists around the world are trying to develop four very different types of quantum computers, based around light particles, trapped ions, superconducting qubits, or nitrogen-vacancy centres in diamonds.

Companies like IBM, Google, Rigetti, Intel and Microsoft are currently leading the quantum charge.

Each method has its pros and cons, but the overarching challenge is the fragile nature of quantum itself.
