Quantum Computer.

lollll Wow... I'm surprised people even comment to these threads.... some of the comments are just W O W..... fukkk u know what? wtf am I commenting here for! 

Bleeghhhhhh I have just realized this Discussion forum is 85% full of B-shit, big time...I cant beleive it has taken me this long to notice the percentage of shit here.. , cubye

If you need more high quality forum for discussing about quantum computing maybe this is right place for you:

Quantum computers will affect bitcoin the same way teleportation or time travel will do.

Quantum computers are real.

So is time travel and teleportation. Quantum computers are just closer to becoming reality. And quantum computers arent really measured as 1000x faster.. instead of doing calculations really quickly one at a time, the quantum computer does all the calculations at the same time. Or something to that effect. It will be exponentially faster than anything we have today. Theres some good videos on Youtube that explain it.

Time travel is not real. You can only "go forward in time" by traveling at speeds that approach the speed of light as it makes it seem like time is going by faster then it really is. You cannot travel backwards in time.

Quantum computers are not a threat as ASICs are already in use on the network which will be more efficient then Quantum computers.

I think a lot of things will have to change when quantum computers come into existence. Im sure we will cross that bridge when we get to it. No point speculating whats going to happen when the computers don't even exist yet.

Yes, it's true. But we can to think about future of mine with so high power. Number of miners will go so low with that machines, i think.

Sure they are. I saw one recently in "zero theorem".

I will start worrying (and educating myself) about quantum computers when they start factoring very large numbers. Until then...same category as interdimensional aliens using advanced technology to hijack the blockchain.

haha 'tis true! Aliens would probably be able to pwn the blockchain using a smartphone equivalent.

It has already been done. So start worrying.

I believe that the NSA has already developed/purchased to help them handle all their data they get from their spying programs. I believe it was also very expensive (in the billions of dollars).

Actually a Canadian Company developed them at $10 million per pop. They were heavily funded by Jeff Bezos of Amazon.com and the CIA. Lockheed Martin bought the first one and a university used one to solve complex equations that were not solvable until this thing came out.

The majority of the scientific community laughs on this project for almost 10 years now.
It's not quantum. Both in theory and practice.
Actually in practice things are even worse with generic computers outperforming d-wave in many cases.

Get over it. There is no quantum computing. There is research but atm with zero results.

Everything that he said is 100% bullshit. I did the research and he is pulling stuff out of his ass.

What did you find?  According to wikipedia, 143 is the largest number ever factored
by a quantum machine.  To me, that counts pretty much as "zero results".

The example in wikepedia concerns sampling raw qbits (like D-Wave does).

The factoring result was stated with X% certainty, where X was <50%, I can't remember the number.

The output was a gaussian spread over discreet bins after multiple runs, the highest bin being the result.

The trouble being that the act of sampling the qbit almost destroys all info, the quantum state being so fragile, many samples are needed to get a result over the noise floor.

However steps are being made toward a "logical qbit" and if it does as advertised then a 2^N number could be factored with one pass on a N qbit system, with 100% certainty.

I think John Martinis is the world leader in this field.

He gives a very nice presentation, covering QC 101 and also the very latest work (logical qbit) that he is doing, well worth a watch for anyone interested:

I want a quantum computer now.

Time to become a multi-bilionaire.

Quantum computer is not (yet) something that Average Joe can go and buy. At the moment it is more government stuff: "According to documents provided by former NSA contractor Edward Snowden, the effort to build “a cryptologically useful quantum computer” — a machine exponentially faster than classical computers — is part of a $79.7 million research program titled “Penetrating Hard Targets.” Much of the work is hosted under classified contracts at a laboratory in College Park, Md."

I've also wondered the same thing a while back when doing homework on Quantum computers.
