Condensed matter theory physicist and quantum information expert Sankar Das Sarma has argued in MIT Technology Review that quantum computers remain a very long way away from cracking RSA-based cryptography.

An example of the methodology in crypto is the creation of a new wallet that generates a public address and private key.

Quantum security is seen as a major issue in the blockchain and crypto sector and it is widely believed that powerful quantum computers will one day become advanced enough to hack current cryptography.

“A quantum computer can take many inputs, do many calculations, and produce many results at the same time.”

Even the most bullish proponents of quantum computing say we’ll have to wait a while until the machines are powerful enough to crack encryption keys, and many doubt it will happen this decade — if at all.
