Yea,thanks, nice links. Was just thinking with my original post that it's probably about time to have some fud spread about the possible quantum attacks on bitcoin given that those chinese researchers have "claimed" a breakthrough. Just noticed someone else posting on SN about it so expect to see more fud running through the usual "crypto" channels.     

Just noticed news.bitcoin.com just commented on the topic too!

Quantum fud incoming?

The security of Bitcoin was designed to be upgraded in a backward-compatible manner and could be [upgraded](https://en.wikipedia.org/wiki/Post-quantum_cryptography) if deemed an imminent threat (cf. Aggarwal et al. 2017, "[Quantum Attacks on Bitcoin and How to Protect Against Them](https://arxiv.org/abs/1710.10377)").

See the [implications of quantum computers for public key cryptography](https://en.wikipedia.org/wiki/Quantum_computing#Potential).

The risk of quantum computers also exist for financial institutions such as banks, because they depend heavily on cryptography when transacting.
