Last month, had to Google to know that they had a quantum computer is built, and that news created a lot of question marks in the bitcoinlandschap. A quantum computer could, in theory, pose a threat to the security and credibility of bitcoin. But are these concerns justified?

The article has since been removed by NASA
The Financial Times wrote at the time on the news, briefly-and it was shared in a website in the us. The article has now been removed and is no longer to be found. In that article, it was stated that the super computer from Google, in 200 seconds, the same amount of calculations it can perform, and if a computer is in a 10,000 year old can do it.
What is it with bitcoin to do with it?
But how can a computer, bitcoin is threatening? At this time, the cost of a quantum computer is still many billions of dollars to develop. Now, let’s say you have a party, so far as to have an extremely expensive computer for only one purpose, to use bitcoin to crack it, then it is expected that, in these two ways:
A quantum computer is more powerful than all the current miners for each other. What miners do is to have a number of boards, and if they are under the doelgetal, then they may have a block to add it to the blockchain. Here, they get a reward for it, i.e. to 12.5 bitcoin. The protocol ensures that, on average, every ten minutes a block is added to the blockchain. Every two weeks the difficulty of guessing the number may need to be modified in order to, which is an average of ten minutes to come out. Could be a day, a quantum computer can be used for mining, then they will be in two weeks ‘ time, perhaps every minute of every day is the right number to suggest. There will be ten times that amount of bitcoin is released. After two weeks of the protocol, the level of difficulty, and all the other miners to eliminate. Also, it’s so hard to be, and that it was only after a year, a new block can be added. Therefore, bitcoin is broken.
Also, can you make a quantum computer using individual addresses to break into. With the private key, you’re in control of your bitcoin. This private key is a hash value and a public key. This is again a hash, for a ship to address to be generated. This is the computer you are on is impossible to have a ship to address to return it to a public key, and then go back to a private key. A quantum computer will it be able to do it closer to home. In theory, you can have all the private keys, and discover all of the bitcoin to you, send it in.
Throughout the internet is at risk, not just bitcoin
So why on earth would you stop bitcoin? In theory, it is in fact not a single encrypted security protection, safe and secure. Just think of all of the servers of the government, the financial data of all banks, and all of the medical information to the public. In short, the whole foundation upon which the internet is built on will have to be reviewed.

Bitcoin fits in
Bitcoin is being constantly further developed and has become be able to get rid of all of the previous attacks. Bitcoin is, after all, has never been successfully attacked. Therefore, it is expected that in the distant future, quantum computing solutions that so far have been to get bitcoin to be subject to the protection of the cryptomunt to be ready for it.
“Cryptocurrencies can be updated to work with the kwantumbestendige technology,” says Charles Hayter, the CEO of bitcoin, and cryptocurrency ” data-site, CryptoCompare. “This is nothing more than a never-ending game between the hackers and security people.”
When we get the news from the Financial Times are to be believed, it is the quantum computer to Google, anyway, is not yet strong enough to pose a threat to bitcoin can be.
Quantum computing solutions that are a long way off
Dragos Ilie is a researcher in quantum computing and encryption, at the Imperial College in London. He is, on this subject, is interviewed by Billy Bambrough, from Forbes: “The super-computer, Google now has a 53-qubits. To be effective in bitcoin to be able to attack, or any other accounting software, you have to at least 1500 qubits are needed”.
Today, computers process information and commands as a sequence consisting of the numbers 1 and 0. Quantum computing solutions that use qubits for you, and that can also measure the polarization of a photon or the spin of an electron.
Ilie says that the quantum computing solutions that are at this moment in time is still at a theoretical schaalprobleem yesterday: “As more qubits are added, the system is becoming unstable. At this point, it is not possible to be a threat to bitcoin as to form”.
In short, you don’t have bitcoin, not out of fear of abandonment.
