Identical wording placing limits on the export of quantum computers has appeared in regulations across the globe. There doesn't seem to be any scientific reason for the controls, and all can be traced to secret international discussions
Drives are usually encrypted with symmetric ciphers (usually AES) and these are reasonably secure against quantum attacks with a key big enough.
And with the vast majority of crimes you just need to wait until the statute of limitations, which in cryptography and quantum fields is quite short period.
Governments are also hoovering up encrypted files and storing them for later so when the time comes, they can go and decrypt everything.
Gov seized your hard drive and you feel safe knowing it’s encrypted, better hope the forgot where they put it in 15 years.
There’s no hiding secrets from the future.
With math you can try, but I bet that in the future they laugh at the half-assed schemes and algorithms amassed to enforce cryptographs in the past.
Not all encryption is vulnerable to quantum.
Drives are usually encrypted with symmetric ciphers (usually AES) and these are reasonably secure against quantum attacks with a key big enough.

…another argument for aggressive statute of limitations for all non-violent crimes.
