Quantum physics is weird. As its a gray fundamental where things can be in two places at once or spinning in two different directions at the same time.
We can normally ignore this absurdity since it only happens at a microscopic scale in any given moment. However, soon machines maybe able to exploit these bizarre features, this could evolutionise computing, but for who and at what cost. Conventional computers store and process information as bits. A bit can be a 1 or a 0. A modern computer chip has millions (even a billion) these electronic switches that can either be on to represent 1 or off to represent 0. The progress in computing over the past 70 years has been to shrink and speed up these switches this makes engineers moderately pleased.
As valves in the re-creation of the Colossus mark II computer. The Colossus was the first electronic computer - these are valves from a recreation of 1944 a version to do number crunches at an alarming rate. A quantum computer works very differently. Because it uses bits tiny particles, either atoms or subatomic particles, these are subject to the laws of quantum physics known as the spark of life as it were. That means they can be in two states of calculating at the same time. Here is the theory so a quantum bit (or qbit) can be a 1 or a 0 or a 1 and a 0 at the same time. This is known as a qbit.

So why might this be an evolution in computing speeds? For all their amazing performance convention as computers. They have their limitations for example, games, language as these are use to benefit human lifestyles. This might solve the problems like the morning rush of traffic congestion.
There are some problems more so difficult that all the computers that have ever been built couldn't even solve. None the less working together as show any way forward. As yet Humanity is still not able to find fundamental answers before sun shards a way into the future. As book-club programmed bubble game for the android system this works off a domain on an android system, where one bubble becomes two or one again depending on its colours as a choice. In short computing has no awareness as its only a programmed task handler. With Computer Optimization as simple as it sounds, for example one can see the sort of problems we their talking about.
In theory imagine a travelling sales representative. He or she has to go to 10 different locations in a day and wants to work out which is the most efficient order to make such visits. This is actually a huge mathematical problem, with more than '3.5 million possible combinations' that each has to be worked out before the best solution can be reached. Its takes a human a million of a second to figure. Suppose by now one was to increase the number of locations from 10 to 20 and there are more than two quintillion possible solutions. (that's 2 followed by 18 zeros). Now consider not cities, but stars. There are 300 billion solar systems in our galaxy. As to where these are as they have moving locations as facing an Earth positions to a fraction of a degree. Not a surprise then that Nasa is very interested in quantum computing. This is an example of what's called optimization of problems and our world is awash with them.
So as from designing the right formula for a new drug trials, trying to get machines to think as if it were like a human or to get humans to program like machines. A quantum computer in theory could crunch this sort of problem pretty swiftly. This is because its qbits are able to consider all the possibilities, as some of the answers at the same time and then pick the best answer sort to speak. Does this sound impressive, but it is as a theory and that's well its up for a debate.
In a world we still need Microsoft to operate a system that is it IBM 386. D-Wave has two quantum computers at Nasa Ames, A D-Wave machine has been installed at Nasa Ames Research Center in California. So how close are we to real quantum computers? A Canadian company D-Wave will sell you one right now. Although there is a lively debate among physicists as to whether the D-wave machine is really a quantum computer or only a three way processor like the i3 sort to speak. (That debate is too technical and kinda of complex to even attempt to summarize here). Closer to home, researchers at Oxford University have succeeded in controlling charged calcium atoms (ions) in a quantum state now that a wow as to ponder. At the moment, the apparatus to do this fills a basement. Shrink this down and add a million or two more qbits and they will have a quantum computer in a calcium form better than an android cleaner, 'doubt it'. That, what they say, its all a box of bolts and is probably a decade or more away even with progress. The physicists involved in this work are very obviously excited to be at the start of a science that could fundamentally important. We need to change our world first as a thought but its not lightly. Here a jump to media player this is one that could help out other players with formats but how about listener. As newsnight's David Grossman explains quantum computers (these computers are not interactive per say) As Laura Mulholland and Dominic Bailey state as in a conjunction with Connected Studios. But Music is the spice of life and a music compilation can be sold easily. But tell that to a music company and they will offer neither, now that's a qbit, thats short for quibble.
