Google has claimed they were able to create the first quantum computer in the world. Can this be a threat to Bitcoin? Several people were concerend by the possibility that quantum computers could disrupt the crypto network, but Peter Todd, an ex- Bitcoin Core developer, doesn’t agree with them.
To understand why Todd doesn’t believe that this will be an issue, it is important to understand what Google actually did. The tech company used its computer to solve an equation that would normally take 10,000 years in around 3 minutes and 20 seconds.
This does not mean that the so-called quantum computer can solve any problem that fast. It was able to solve that specific problem so quickly because it was devised to do it. This is the most important point here.
The developer affirmed that what Google achieved was only a very primitive type of breakthrough. The company was nowhere near being able to break something as complex and powerful as Bitcoin.
He affirmed that the scientists involved in these experiments still don’t know if it is really possible to scale quantum computers without having huge costs. Because of this, they are mostly used for tests in order to develop the technology, not to solve any actual issue.
The U. S. National Security Agency (NSA) was recently reported to be attempting to create its own quantum computer. In this case, crypto's would be far more endangered than if Google did it, but it is still hard to confirm that this technology can or will be a threat any time soon.
