Google claims to have built the world’s most powerful quantum computer. Quantum computers are more efficient in accomplishing certain mathematical problems by accomplishing this by magnitudes. Quantum computing is the area of study focused on developing computer technology based on the principles of quantum theory. The biggest danger to the Bitcoin industry from quantum computing is its ability to break traditional encryption underpins it, which could potentially mean the encryption used in Bitcoin and other crypto-cryptic networks could be at risk. Google's experiment is the first experimental challenge against the extended Church-Turing thesis — also known as computability — which claims that traditional computers can effectively carry out any “reasonable” model of computation.
