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
Anything that’s “30 years away” is essentially not going to happen. Quantum cryptography will advance faster than the ability to break it because there will be more money behind it.
That’s not really the concern, quantum cryptography already works, we have more robust encryption techniques.
The problem is that the planet has a whole lot of saved communications still encrypted with old techniques, and those are all at risk of being decrypted later. If you were transmitting encrypted data, knowing that there’s was a man in the middle, you probably felt pretty clever, as even the watchers couldn’t read it… But they could record it and save it. Now all those saved recordings are likely to come out.
