Why haven't quantum computers factored 21 yet?

[Michael Katzmann]

"If you are to believe the glossy marketing campaigns about ‘quantum
computing’, then we are on the cusp of a computing revolution, yet back in
the real world things look a lot less dire. At least if you’re worried
about quantum computers (QCs) breaking every single conventional encryption
algorithm in use today, because at this point they cannot even factor 21
yet without cheating."
