Multiple nations enact mysterious export controls on quantum computers

Secret international discussions have led to multiple countries imposing identical export controls on quantum computers without disclosing the scientific basis behind these regulations. Despite the potential national security threat posed by quantum computers breaking encryption, current public quantum computers are too small and error-prone to achieve this, making the bans appear unnecessary. The UK, France, Spain, the Netherlands, and Canada have all implemented export restrictions based on qubit numbers and error rates, with the UK citing cyber risks as a reason. These controls align with the Wassenaar Arrangement, a system followed by 42 states to regulate dual-use technologies. While some countries are closely monitoring the situation, the lack of transparency regarding the rationale behind these restrictions has raised concerns about stifling innovation in the quantum computing industry. Christopher Monroe, co-founder of IonQ, highlighted the potential negative impact of limiting research progress in this field.

This is reminiscent of the US government considering PGP (Pretty Good Privacy) with keys larger than 40 bits to be munitions and so could only be exported under license.

Sounds very much like someone did some theoretical work that said at 34 qubits you can do something interesting, and then other nations started copying the restriction while trying to figure out the why...

Very interesting, anyone have any insight into why 34 qubits was chosen?

Because reliable quantum computers with a large number of qbits can, in theory, break traditional encryption schemes relatively easily (once you have the tech) and a lot of our society, economy, national security, and privacy relies on traditional encryption schemes.

Someone in charge looks at the potential harm a thing can do by imagining themselves in a sociopath's shoes and gets justifiably scared. Dan Brown or Tom Clancy gets to sell another book, etc.
