Chinese researchers claim they can break 2048-bit RSA using quantum computers
indiatoday.inAs always, extraordinary claim require extraordinary proof.
No need for any extraordinary proof.
Start by factoring the RSA Factoring Challenge.

Obviously there are ways to cheat on this challenge, such a cyber attack on where RSA Inc. stores the results, but it would be a great start.
Pretty directly testable, although I suspect nobody will test.
I agree. At least just publish the solution of RSA260 in https://en.wikipedia.org/wiki/RSA_Factoring_Challenge
