Vitalik Buterin Says Google’s Quantum Technology Has Yet to Find a Useful Application

Vitalik Buterin, the creator of the Ethereum Network, is not impressed by Google’s most recent claim. A paper published by the tech giant just recently states that it has finally achieved quantum supremacy, a technological wonder that can solve problems that are practically impossible for classical computers.  

On October 23, Buterin sent a tweet that highlights his nuisance about Google’s announcement that it has successfully solved a complex equation in 200 seconds. In contrast, the world’s traditional computer would have taken ten years to resolve. 

Buterin went on to compare the quantum supremacy to the relationship between nuclear fusion and hydrogen bombs. He noted that while the technology had already proven its capability, Google has to find an area of application where it could be proven useful. 

Quantum supremacy has no power over Bitcoin

Earlier this month, Andreas Antonopoulos, a Bitcoin (BTC) educator, reiterated the same sentiments towards the technological wonder. He mainly discussed the claims of some industry analysts that quantum computing poses significant threats to Bitcoin and other cryptocurrencies. However, Antonopoulos emphasized that Google’s quantum technology can do nothing at all against Bitcoin. He noted that Google had only demonstrated the quantum computers’ practical ability in solving specific types of problems. However, these issues are entirely different from the class of problems associated with cryptography. 

As theorized by industry experts, quantum computers’ ability to perform complex calculations in an extremely swift manner can jeopardize the proof-of-work mechanism of Bitcoin and Blockchain technology. Reportedly, the calculations performed by Google’s quantum computer can easily outperform the system of modern cryptography, ultimately reversing crypto transactions and gaining access to users’ private keys. 

However, a quantum theoretician from the University of Texas at Austin, Scott Aaronson, published a research paper that suggests a potential application of quantum computing in proof-of-stake cryptocurrencies. Notably, a sampling-based experiment that has been carried out using quantum supremacy can be repurposed to generate genuine, random bits. As emphasized by the researcher, quantum computing application could assuage the doubts of skeptics towards PoS variants.
