Well, since they created the internet first, and then bicoin, they will probably find a fix for it as well. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

From here, it makes complete sense to send your stash to a newly created paper wallet that have never been used to spent from the address, in effect makes the public key never been exposed to before on the blockchain.

Another 'noob' who did not understand D-wave did not make a true quantum computer, and posted a sensational title in an attempt to drive price down.

But dude, when you transfer coins to an address, everyone will know if you like it or not. It is a feature of the blockchain. You cannot hide your coins.

I now try to never reuse an address again, it makes sense. (does the brilliance of bitcoin ever stop? wow) Thanks for clearing it up!

This is science fiction at best. Dude just calm down sit and relax, in our lifetimes at least, we'll not see anyone cracking the SHA 256 hash. The blockchain is safe my friends.

Saved in my favourites. Personally, I don't really know whether this is a true Quantum computer or not, I just put this here for comment from everyone else. But when SHA is eventually cracked and a thing of the past, I will definitely repost this one :-)

A single hash has a gazillion solutions and even if you knew all of them you'd still need to test each one of them.

Just to clarify - the fact that I can go to blockchain.info after I send coins to a paper wallet address, type in that public key, and it is displayed on the screen with the proper balance - that isn't the public key being "revealed" to the network? -B-

The address is derived from the public key through a 1-way transform. https://en.bitcoin.it/wiki/File:PubKeyToAddr.png

Also LOL at the notion that D-Wave can crack Bitcoin. Their product is interesting but it's not really a quantum computer and, to date, hasn't offered much performance benefit over classical computers.

You can protect your coins on a new address but you won't be able to spend them. Once you decide to do so an attacker will get your private key and will send the money to himself. You have to send the transaction directly to the miner without revealing it on the network.

largest number factored on a quantum device is 56,153. (a 16 bit number).
we're a ways off.
if it ever became a threat, Bitcoin would upgrade.
