Commercial quantum computer actually works, according to new testing

Since the Canadian company D-Wave began selling so-called quantum processors, experts have debated whether they're truly quantum. Now, according to an analysis by academic physicists they really do show quantum effects, making them the world's first commercial quantum processors.

In general, it's been difficult to confirm how D-Wave machines work because quantum states are so sensitive, measuring them may perturb them. Besides this new test, performed at the University of Southern California, a few different recent tests have gathered evidence that D-Wave processors work as advertised.

Quantum processors have quantum bits instead of the usual binary bits that traditional processors have. You know normal bits store information by taking on one of two states, often named "0" and "1." Quantum bits, also called qubits, have another capability. They are able to take on both the 0 and 1 states at the same time.

In Engineering, the Results May be More Important than Principle

All I was looking for was how much faster this processor is than what would normally be used.

Disappointingly, the only articles I've seen give useless figures:
for example, only giving the speed of the quantum processor and no comparative figures.

So, less than a second to solve a problem?
Compared with what?

If it normally takes a minute on a super computer, then i get to say, "wow, it's at least 60 times faster".

However, I appreciate the post and will now keep an eye on current quantum processors.

Thanks.

checked into this story about D-wave

There is still a big controversy over the question of whether or not D-wave has achieved "Quantum computing" or "Quasi Quantum computing".

so, they think mebbe the effects might indicate the existence of.

right, got it.
