Quantum computers put blockchain security at risk - Bitcoin and other cryptocurrencies will founder unless they integrate quantum technologies
This is the best tl;dr I could make, original reduced by 91%. (I'm a bot)
The solution is to develop a quantum repeater, which uses quantum teleportation and quantum optical memory to distribute entangled states between the communicating parties. Using quantum technology for communicating as well as for the computational processing of blockchain data would further enhance security and enable blockchains to become faster and more efficient. This step requires a 'quantum internet'10 - connecting quantum computers across a quantum communications network. The proposed Quantum Bitcoin currency could be realized, with its security assured by the no-cloning theorem of quantum mechanics. Such quantum 'bank notes', if they still prove necessary in future, could be made impossible to forge by containing quantum information records11. The longer-term answer is to develop and scale up the quantum communication network and, subsequently, the quantum internet.
Bitcoin mentioned around Reddit: Google on track for quantum computer breakthrough by end of 2017 - "The company is testing a 20-qubit processor – its most powerful quantum chip yet – and is on target to have a working 49-qubit chip /r/technology
Quantum computers have the capability to crack complex mathematical problems as qubits or quantum bits can maintain a “superimposition” by being in two states at a given time. Meanwhile, Marchenkova doesn’t think crypto holders must find a way to move their Bitcoin to a quantum secure wallet immediately. But she does believe anyone ... Humanity currently does not have the technology necessary to create a quantum computer large enough to attack Bitcoin keys. It is not known how quickly this technology will advance; however, cryptography standards such as ECRYPT II tend to say that Bitcoin's 256-bit ECDSA keys are secure until at least 2030-2040. There is a company called D-Wave which claims to produce quantum computers with ... Quantum computers uplifted technology which includes nodes running on Quantum computers. What threat is caused to crypto algorithms as well as to blockchains by quantum computing? Influential quantum computers may become a threat to blockchains that depends on ECDSA, which includes Bitcoin and Ethereum. ECDSA has got a golden stand in developing solutions under public solutions. Most ... Quantum computer may not help unlock lost Bitcoin, it is believed, at least not yet. A bitcoin wallet worth $700k is up for grabs to anyone who can crack the password which seems to be lost. Alon Gal requests for a Quantum computer in his tweet, to aid cracking the password and this has brewed controversies as to the security of the Bitcoin wallet. But there is one opportunity for quantum computing. Touching the Bitcoin network would almost certainly be a touch of death. Even if a quantum computer mined merely 2016 blocks, in theory this would raise the difficulty so high that regular mining equipment would take an impossibly long time to create another 2016 blocks and reduce difficulty.
