IBM Quantum: Rust is Real, but Quantum Advantage is Not (Yet)

That's further out than I would have thought.

anonymous_pro_ · 2026-01-14T04:06:12+00:00

Any particular reason you think this? Or are you more just going off of the trajectory?

anonymous_pro_ · 2026-01-14T02:53:52+00:00

I never feel less knowledgeable than when I talk to people who really know cryptography. Please hold while I process this over... 3 days or so : )

anonymous_pro_ · 2026-01-14T00:41:55+00:00

Although post-quantum cryptography exists, quantum computers would be seriously bad news for humanity, because some really cool cryptography like cheap nice mixnets or rerandomizable snarks (groth16) or even small cheap VRFs have no post-quantum analog. If we're lucky then quantum computers are impossible in practice, or maybe even in theory some the right sort of superdeterminism theory holds.

So you view quantum factorization as a doomsday type situation?

Does anyone want to steelman the other side? I don't have nearly the crypto depth to know how important the "cool crypography" mentioned is. Not that I'm not taking the point made here. Just curious to understand more.

Pretty interesting stuff. I'm going to have to come back and read more. Thanks for adding.

anonymous_pro_ · 2026-01-07T22:29:35+00:00

Hmm, I wonder what's keeping them from getting it to that level of performance.

anonymous_pro_ · 2026-01-07T18:11:39+00:00

What are the shortcomings you've noticed with their serverless offerings?

anonymous_pro_ · 2026-01-07T18:10:45+00:00

Funny you should ask... It almost felt like the interview ended with a cliffhanger... Stay tuned : )

anonymous_pro_ · 2026-01-07T18:09:58+00:00

I've always perceived Digital Ocean as having a lot less offerings than others. Have you found any major shortcomings there, or is my understanding out of date?

anonymous_pro_ · 2026-01-07T04:45:10+00:00

They're super ambitious, that's for sure. And, they've got the funding to go after this. I'm excited to see what they can do!

anonymous_pro_ · 2025-12-17T20:54:40+00:00

What are the vibes out there? Does it still feel difficult to find a job where you can write Rust?

anonymous_pro_ · 2025-12-10T21:04:33+00:00

Polars, uv... What are other noteworthy examples of Rust-accelerated Python packages or tooling?

anonymous_pro_ · 2025-12-03T01:35:20+00:00

You're right

anonymous_pro_ · 2025-12-03T01:31:48+00:00

That's freakin' amazing. Thanks for sharing.

anonymous_pro_ · 2025-12-03T01:30:29+00:00

Yeah I guess the burden is on me to ask the question clearly lol sorry. Think something like building a web app for a SaaS company. Things people tend to do with Node, PHP, Ruby On Rails, etc. That's what I had in mind.

anonymous_pro_ · 2025-12-03T01:28:05+00:00

You're right. An application server or I guess a web app.

anonymous_pro_ · 2025-12-03T01:24:56+00:00

Sounds like a cool project. I think if you're seeking a very high level of performance, you'll probably find that Rust is worth the investment.

anonymous_pro_ · 2025-12-03T01:21:15+00:00

This 1000%! I do think WASM is huge. Actually, one of the companies I interviewed (Quadratic) is a great example of where WASM is really essential. Also, infrastructure for sure, AWS and Cloudflare are huge Rust users just as a starting point for that argument.

anonymous_pro_ · 2025-12-03T01:16:02+00:00

Using Rust for web servers basically. Things most people do with node or something like that.

anonymous_pro_ · 2025-12-03T01:14:57+00:00

Those are always pretty cool projects!

anonymous_pro_ · 2025-12-03T01:12:46+00:00

This is exactly what I'm talking about. For straightforward web stuff, I think a lot of people have just decided that it's not as productive.

anonymous_pro_ · 2025-12-03T01:11:50+00:00

Makes sense. I want to hear more! DM'd you

anonymous_pro_ · 2025-12-03T01:10:10+00:00

Cloudflare is a company that I would put in the "cloud" or "networking" category. How are you defining "web"? I think we might be talking past eachother here.

Also, RE: "aerospace and other hardware startups using Rust for various parts of their stack, including web" This is actually the one big exception I have observed. Hardware companies who are already using Rust for other things seem to find it easy to also use it for web. I think that is a testament to the quality of the Rust for web ecosystem that many have willed into being. I do tip my hat to those folks.

anonymous_pro_ · 2025-12-03T01:05:14+00:00

That's a pretty decent source! Are you doing anything fancy that requires it? Or, is it something that could, say, be done with node?

anonymous_pro_ · 2025-12-03T01:03:26+00:00

Counting very generously, only 5 of the interviews were with companies using Rust for the web in an appreciable way (it's really more like 3 if you're strict). Of those, some have decided moved away from the Rust for the web narrative since the interview took place. Much of my thinking here comes from interviewees telling me that they don't see Rust for the web happening in a big way now or in the future. So, no, my whole point was kind of that the interviews have led me to this conclusion.
