 Researchers from The Australian National University (ANU) have developed a method of freezing and storing light, an important step on the road to developing quantum computers. Most switches used in quantum computing experiments are made up of trapped ions or semiconductor particles, suspended in a state of quantum superposition. Photons, however, could interface much more efficiently with fiber optic networks, without the need for a way to translate the information between the qubit — the quantum-computing equivalent of a classical computer bit — and the computer’s network or interface.

The director of the Federal Bureau of Investigation, James Comey, is advising computer users to protect themselves from having potential hackers spy on them using their webcams, by simply putting a piece of tape over the lens.

Comey says that this is standard procedure in government offices, and that it would be prudent for normal citizens to follow the same practice. He began covering the camera on his personal computer after seeing the issue covered in the news. Facebook founder and CEO Mark Zuckerberg is also known to cover his webcam up, too.

Because of the physical limitations of silicon-based circuitry, there is an upper limit to how powerful a modern computer can be made. In response to this, researchers have been looking into other mediums to build faster and more powerful computers from, including using quantum-based processors, and neurological chips based on human brain cells. Another promising idea, based on DNA, plans to utilize the otherwise naturally-occurring computer of genetics.

A growing number of scientists are starting to seriously consider the possibility that we are living in a Matrix-like computer simulation, including influential physicists such as Dr. Michio Kaku. And some are actively looking for scientific clues as to whether or not this is a constructed reality, as a team of researchers from the University of Bonn in Germany are doing, looking for patterns in simulations of the mechanics of the universe, and seeing if those patterns also hold true to "real life".
