New world's first commercially available quantum computer

D-Wave, the world's first and so far only company making quantum computers

As is put above in the screenshot

Would the computer shown that looks like a desktop box fit inside your room?

Well the answer, will surely be NO

Because if you read the description shown here

The D-Wave TwoTM system is a high performance computing system designed for industrial problems encountered by Fortune 500 companies, government and academia. Our latest superconducting 512-qubit processor chip is housed inside a cryogenics system within a 10 square meter shielded room.

And considering that additionally that it ocuppies 10 square meter on the floor, also it is very high as seen better in this other photo taken from here



So as I have said, I doubt much that you will be able to have space for this computer

If you are like myself, I did not know what a qubit was, but looking in the Wikipedia and also in this other website with a definition for qubit

In short a qubit is a quantum bit.

From wikipedia A qubit has a few similarities to a classical bit, but is overall very different. Like a bit, a qubit can have two possible values—normally a 0 or a 1. The difference is that whereas a bit must be either 0 or 1, a qubit can be 0, 1, or a superposition of both

To know more about this new available computer announced in May 2013 can be seen here

Quantum computing VS standard computing (the ones we have now)

And to know more of what is the brain and force inside this "cube" you can look at the photos shown in this news that explains much more about it and it´s perfomance speed too

PERFOMANCE SPEED

According to this article shown here in the above last link, perfomance speed of this quantum computer is 420 GigaFLOPS

You may think, how much is this? And how it compares to my computer?

I am searching for it to see How many GFLOPS perfomance speed does have a normal desktop computer have

PRICE

The main problem is NOT that this computer is big, the real problem is that it costs about $10.000.000, much cheaper to all those multimillion dollar computer from important companies, but anyway, I think that none of us in this forum will be able to buy any of this quantum computers
