Comment on Breakthrough promises secure and private quantum computing at home

  It’s still not your hardware, so you can’t rely on the data being private to you even if the connection is secure.

  Then there’s going to be all the politics present with the location of whatever endpoint you connect to, issues of uptime and availability, etc.

  It’s a matter of the threat model you’re concerned about, but this does not fill me with confidence if this is considered a “breakthrough solution”. There’s nothing quite like a half assed solution to kneecap work on a “proper” one.

    From the article:

    Using blind quantum computing, clients can access remote quantum computers to process confidential data with secret algorithms and even verify the results are correct, without revealing any useful information

    This is a breakthrough because this level of security is impossible currently (as you allude to in your comment).

    Availability will still be an issue, of course.

  I read it but I didn’t see anything about local quantum encryption. Originally my comment talked about that until I realized they are just talking about accessing cloud-based quantum encryption. So I immediately edited it not to look like an idiot. If I’m still missing something, let me know, but I am not seeing it.

    My point is that the article is about making cloud quantum computing secure; the article doesn’t even mention quantum encryption.
