Divided opinions among experts as to the practical implications of quantum cryptography

Scientists in China were able to change a cipher key at a distance of 1,120 kilometers, surpassing the previous best attempt of 1,000 kilometers. Crypto coin experts are discussing whether this could have practical implications for the industry.

Hacker-proof cryptography?
Quantum computers have been the scarecrows of the crypto industry for years, and some speculate that advances in this technology will make all existing cryptography obsolete, this time quantum Bitcoin Revolution entanglement was used to change a secret key that could be used to encrypt and decrypt messages. One could imagine that if this technology becomes commercial, it would make encryption hacking obsolete as well, since users would be able to perform transactions outside the Internet.

We contacted cryptography experts to find out if this technology could have practical implications for the industry in the near future.

Not in our lifetime
Cornell University professor and co-founder of Ava, Emin Gün Sirer told Cointelegraph that he had been waiting for this technology for the last 40 years. He believes it will come in handy sooner or later. „Yes, I’m still waiting! I first read about this in the 1980s. At some point, it will be practical,“ he said.

But the developer of Bitcoin Core, Wladimir van der Laan, doesn’t think it will be adopted for viewing during his lifetime:

„Realistically, I hope it will be a long time before quantum computers are available that are common enough to be applicable to a decentralized network, if ever (like: not in my life)“.

Very expensive

Ian Grigg, the inventor of the Ricardian Contract and a notable cypherpunk, does not believe that quantum cryptography has anything practical to offer:

„Nope. We don’t need quantum cryptography to distribute keys securely. We can do it with cheaper software methods.

Sergio Demian Lerner, a Bitcoin researcher (BTC) and RSK designer agrees with Grigg that there are cheaper ways to do the job:

„There’s no need for a quantum link to exchange keys, just travel once and exchange the keys, then use those keys for the next 10 years. In my humble opinion, it has absolutely no application that can cover the cost of the infrastructure“.

While waiting for the progress in the quantum field, Lerner has noticed an interesting new pattern in the way Satoshi Nakamoto was mining.
