i think you people didn't watch the video or didn't read the news.

QUANTUM COMPUTER IS HERE. IT IS NOT A TECHNOLOGY FROM FUTURE. IT IS HAPPENING, IT IS HERE.

And yes, bitcoin is a target. YES IT IS. It has too much value right now.

And 'they' only need ONE (yes just one) quantum computer to destroy bitcoin completely. Not mass production, BUT JUST ONE!

they can only broke ecdsa, if you send bitcoin and not receive only, to not reveal the public key if not mistaken

sha256 is immune

noo.... they havent made one yet. in the video he says they made a logic board with only two qubits. its going to take alot more than that to destroy bitcoin.

what is the future of bitcoin with quantum computers?
https://www.youtube.com/watch?v=-kTDmsNumVE

The creation of an quantum computers is a huge step ahead in the computing science. It will be a big materialization which will help the human being in to many areas. I am not a scientist or a specialist in this field but I already read some things in Wikipedia about it. The news which are in the youtube video are not yet there. And I cannot understand the spoken English to hear it. But I think that if bitcoin is in risk with this computer the developers certainly will find a way to protect it from this kind of computer. Bitcoin cannot have such end.

In expectancy of this development here is an article which give an idea (solution) about how to protect bitcoin from such computer. This solution is named Lamport signature.

The article about the solution can be found here: https://bitcoinmagazine.com/articles/bitcoin-is-not-quantum-safe-and-how-we-can-fix-1375242150

While who want to know more about Lamport signature can read here: https://en.wikipedia.org/wiki/Lamport_signature

Don't have fear. Have faith and hope. This must think every bitcoiner.

Not at all. The feats of quantum computing in the current day and age are far from being threatening and have no competition against the best computers we have now. It will take ages for a quantum computing to do anything that can be considered threatened to current day technology, so don't worry about that.

Can this mean that within some years not even the Blockchain security technology can protect us for Hackers?

quantum computers aren't technically here yet. its just a logic board. but if they were, i wouldn't expect them to be used to crack private keys, that would be using wayy to many resources just to crack a bit of a cryptocurrency. highly inefficient.

i would be worried more about the chances of bitcoin to survive, before the quantum pc will ever hit the market on a large scale

it doesn't need to hit the market on large scale...

right now bitcoin with its silly marketcap would not be a primarily target of hidden quantum computer, other big targets would be in the list before bitcoin

Quantum computers are such abstract, that you can't predict anything. Many said they developed quantum computer before, noone did in reality.
Cryptography will be more vulnerable and with it bitcoin but its same stuff like cold fusion, 30 years of development, nothing in sight in next 30 years.
