Yesterday Google shared a preview of Bristlecone, their new quantum processor. The purpose of the new gate-based superconducting system is to be a testbed for research into system error rates and scalability of their qubit technology, as well as applications in quantum simulation, optimization, and machine learning. This device uses the same scheme as their previous 9 qubit liner array technology for coupling, control, and readout, but is scaled to a square array of 72 qubits.

This is where I usually put my own insight or a witty remark, but since I only know what about 4 words mean in the entire release, I'll just say "neat!"

We are cautiously optimistic that quantum supremacy can be achieved with Bristlecone, and feel that learning to build and operate devices at this level of performance is an exciting challenge! We look forward to sharing the results and allowing collaborators to run experiments in the future.
 
So, I tried reading up on qubits a while ago...but I'm so versed in standard binary logic that it blew my fuse er...mind.

Don't worry about it. I think only a handful of people really understand quantum computing. Standard computing is very deterministic. The process from A->B is easily described, even though cpu wise it can be extremely complex.

From my understanding of quantum computing there is no deterministic path from A->B. The terminology is so weird that they want you to believe that they're forming alternate universes which solve A->B then tossing away the ones that don't get to B.

And just as assembly language was created to make it not necessary to program in machine language and FORTRAN, COBOL, BASIC etc. were created so you didn't have to learn assembly I think most of the details and a deep understanding of it will be left to the "qulanguage" complier writers, the rest of us will just be able to write programs that will take advantage of the underlying power of quantum computing without having to know to many of the details. Sure a deep understanding will probably make you a better programmer, but not necessary to get the job done.
 
We all know where this is going.

Awesome. More GPUs for everyone then.

In fact, if someone would be able to write a mining program using quantum cpus and it was really good at it, just flooding the market and withdrawing all the value before selling the program would net someone millions or billions.

Yeah...doesn't really show it in the article, but despite the cute "normal" looking processor in the photo, these things require huge enclosures to be cooled to near absolute zero. So probably gonna be awhile before we get one in our homes. ;)

About the same time as those room temperature super conductors that always seem to be just around the corner. As to needing those temps, well N. Korea could probably set something up like that...but have to wonder if they would be fast enough to compensate for the high electrical use. Of course until they become cheap for everyone it means some, like the NSA, are going to have a big advantage decrypting things.

Yeah, but the potential is far, far more. Quantum computing would be able to figure out the crypto that is behind the currency. If a qcpu can break the crypto in a second, there goes all of the time that crypto is based on. Plus side, GPU's are available at MSRP's and below. Bad side, cryptocurrency would have to be made so hard to mine that a qcpu would take a month, but the john doe multigpu setup would take a year.
 
When binary math was first invented it was a useless oddity.

Does quantum computing have a practical use as yet?

Is it the new Binary or the new Edsel?

It's more promise than anything yet. But if it proves practical it may indeed be the next computer revolution. There is one company selling "quantum" computers, if I remember they are like $10,000,000 a pop. But think of those early main frames and how expensive and limited they were (in today's dollar), it's early days yet but the potential is there.

Damn... I need to invest in quantum computing lol
 
The correct cartoon for quantum computers and bitcoin should probably be a computer draining everyone's wallets.

Here Hector entered, with a spear eleven cubits long in his hand; the bronze point gleamed in front of him, and was fastened to the shaft of the spear by a ring of gold.

Google, what a nice processor you have there, you could cure disease and help science...

All the better to serve you ads and censor youtube videos with my dear...
 
I've watched tons of videos on quantum computing and I'm still not really sure how it works. I get that each qubit is spinning in both directions (so it's effectively a 1 and a 0 at the same time) right up until the point it's measured, at which point it chooses a specific value.

My best understanding of the benefit of quantum computers is that they are capable of spitting out multiple correct answers to the same problem at the same time due this attribute, which is why it's so good for breaking encryption and whatnot.

But if someone can explain if I'm correct or why I'm wrong it would be greatly appreciated, I'm just having trouble wrapping my head around the whole thing.

It's like computing with spinning coins- when the state is measured the spinning stops and you only get to see the heads and tails. The art of quantum algorithms is in manipulating the probabilities in a way which will give useful information when you read this result.

I get that part (sort of) but what I find confusing is WHY are they better than traditional binary computers.

Simply put a quantum computer can track x number of states equal to the number of qbits. For example the traveling salesman problem, finding the shortest path to visit all places grows exponentially with the number of places in traditional computing. with a quantum computer that problem grows at either a linear or constant rate on a system with enough qbits.

Exactly look at the problems it is said to be especially good for: mapping; chemistry (chemical reactions), supply chain and logistics, encryption/decryption... all things that grow complex rapidly.
 
'Neat' is about all I can say about this too. (insert gratuitous Bender camera image here ____ )

Well, maybe one thing more. A metaphor I have read that drove home the paradigm shifts this technology could bring about. With current tech we can represent two points at polar opposites on a sphere. Qbit tech has potential to represent all possible points on that sphere at the same time. Physical memory size is exponentially reduced as well. Can only hope I live long enough to see such things come to fruition at a consumer level.

The thermal side needs a whole lot of fixing (I mean we're talking fusion levels of engineering here) before we'll see quantum annealers at room temperature. These suckers work near 0 K.

We are going to be reduced to computer maintainers soon enough. The computers will do the engineering. ;)
 
So how far off are we before this makes cryptocurrency worthless due to somebody brute force cracking it?

Fairly long, apart from this all still not even approaching any practical implementation, most cryptocurrencies are already quantum resistant.
