THE QUANTUM COMPUTERS ARE COMING...right? We got Samuel Jacques and John Schanck at short notice to answer that question plus a bunch of other about error correcting codes, logical qubits, T-gates, and more about Google's new quantum computer Willow.

Nothing we have ever recorded on SCW has brought so much joy to
David. However, at several points during the episode, we may have witnessed Matthew Green's soul leave his body.

Our esteemed guests Justin Schuh and Matt Green joined us to debate whether `Dual_EC_DRBG` was intentionally backdoored by the NSA or 'just' a major fuckup.

With the 2024 United States Presidential Election right around the corner, we talk to an unnamed guest who has worked on cybersecurity for political campaigns in the United States since 2004. We recorded this in late August, 2024.

We finally have an excuse to tear down Telegram! Their CEO got arrested by the French, apparently not because the cryptography in Telegram is bad, but special guest Matt Green joined us to talk about how the cryptography is bad anyway, and you probably shouldn't use Telegram as a secure messenger of any kind!

We talk about CrowdStrike in this episode, but we know we made some mistakes:

• The sys files may be code in addition to data.
• The bug might be bigger than "just" a null pointer exception.

Luckily, none of that is actually relevant to the main issues we discuss.
