SOMEWHERE in California, Google is building a device that will usher in a new era for computing. It’s a quantum computer, the largest ever made, designed to prove once and for all that machines exploiting exotic physics can outperform the world’s top supercomputers.

And New Scientist has learned it could be ready sooner than anyone expected – perhaps even by the end of next year.

It exists already. IBM has a cloud based quantum computer. You send your problem to them and it will solve it for a fee. The quantum computer solvable problems are things that would take countless years to compute. For now that's where the advantage of QC lies, raw, complex calculations...

For instance, the power of an "Artificial Intelligence" has to do with the amount of data it can process and learn from. When the data is huge and all the mutual relations near infinite, a classical computer can't compute all of it. But a QC can. 

I remember my first computer had a processor of 8 bits, with each bit taking 2 possible values ("0" or "1"), that would give 256 combinations for each instruction, a set of 8 bits (byte)

But now they already have a processor of a 16 qbits ("qu_bit") . The difference is not the same as a 8 bit to a 16 bit (256 to 65536) because a qbit can take more than the classical 2 values ("0","1" or "ON","OFF" or "yes" and "No")

Each qbit has a superposition of values has in a probability wave. In a two slit experiment of Quantum Mechanics, a particle didn't pass by the hole 1 or hole 2, but rather a probability wave passed by both holes and after we have a superposition of probability waves describing the probability of find the particle in any specific point. That's the same with a qbit which doesn't have a "ON"/"OFF" state but a superposition of both conditions (like the Schrödinger cat that was both dead and alive)

That this gives an amount of possibilities that we can't just imagine!!!
