Two-Photon Walk a Giant Leap For Quantum Computing 112
ElectricSteve writes "Research conducted at the University of Bristol means a number of quantum computing algorithms may soon be able to execute calculations of a complexity far beyond what today's computers allow us to do. The breakthrough involves the use of a specially designed optical chip to perform what's known as a 'quantum walk' with two particles ... and it suggests the era of quantum computing may be approaching faster than the scientific establishment had predicted. A random walk – a mathematical concept with useful applications in computer science – is the trajectory of an object taking successive steps in a random direction, be it over a line (with only two possible directions) or over a multi-dimensional space. A quantum walk is the same concept, but translated to the world of quantum computing, a field in which randomness plays a central role. Quantum walks form an essential part of many of the algorithms that make this new kind of computation so promising, including search algorithms that will perform exponentially faster than the ones we use today."

Just open your eyes, and see where you are. After seeing it you are not going to be anywhere else, but before looking, I can't really tell you.

Microsoft is coming out with Windows Quantum Edition. It only BSOD's when you are observing it; and is in an undetermined state when you are not. How is that different from regular Windows you ask? Well......um...

Two photons walk into a bar, orders a round of IPA and asks "How much do we owe?"
The barkeep says "For you? No charge."

Then they walk into a church and are turned away by the priest. He says, "No mass for you."
