Did the Quantum Apocalypse really arrive on January 4th?
Chinese researchers are reporting they can break RSA encryption with a contemporary Quantum Computer. Can they?
This is a brief post in response to the current focus on the topic. Something longer will follow.
Q: Will quantum computers defeat encryption?
A: Yes, certain types on encryption, including many that are in common use today.
Q: Do we see that as an immediate, existential threat?
A: No. Or, at least we didn’t a few weeks ago as the timeline for suitable quantum computers to be here was “years away”. The recent paper published by researchers in China has raised some interesting questions.
The paper was published a few weeks back but the news got into the mainstream press on 4 Jan and my inbox has been buzzing ever since.
