Google has already claimed that they achieved quantum supremacy. It's a revolutionary in the computing world. I think that through it could help boost the computing power of the blockchain to produce much bitcoins than our present computers.
I heard lot of buzz generated from the announcement coming from Google on its eventual achievement of Quantum Supremacy. However, not many details were supplied by Google on this so maybe we should wait for future announcements that can clarify many of our own assumptions. Can this thing be able to really crack Bitcoin? Can we instead use its power to maybe enhance Bitcoin mining and any other Bitcoin processes? The idea that instead of it killing Bitcoin, we can use to help Bitcoin is really good but how things will be working remains to be seen.
On the other hand, there are those who believe that in reality quantum technology can't be able to touch Bitcoin as it is already resistant to such a threat. We will know which camp can be saying the truth once the technology can be tested against Bitcoin. Let's hope that Google will not be playing an evil Tasmanian in this case and will instead use and safeguard the technology for the benefits of all parties.
