Google gets an error-corrected quantum bit to be stable for an hour
Google gets an error-corrected quantum bit to be stable for an hour
Using almost the entire chip for a logical qubit provides long-term stability.
I flipped a coin behind my couch like 4 years ago. I'm pretty sure that bit is still stable, whichever side it landed on.
Congrats man
You wanna know what the secret error correction is?
Super glue. Don't tell Google though.
It's not quantum any more. It was observed by your cat.
I keep reading about Quantum computing and while I understand the use cases and the general operating logic, I still find it difficult to get how it works on a technical level (I've watched/read multiple explanation content pieces).
I wish there was something like Ben Eater's "Building an 8-bit breadboard" series for quantum computing. It's pretty dense, but even watching it on the second monitor did give a useful perspective on how CPU's actually work.
I don't think it's really a topic accessible by the layman right now at that level.
You need billions of dollars and thousands of hours to build and operate a quantum computer currently, and the cutting edge (i.e. the stuff that's getting close to being usable) has a large amount of information locked behind proprietary trade secrets.
There's several high level videos out there explaining it, but if you're looking for a nitty-gritty walkthrough like Ben Eater's videos, you're going to be waiting a good number of years, IMO

The high level videos are fine, but I haven't seen any content pieces that explain how quantum computers are built and operated from base principles. I recognize that there won't be any "build a basic quantum computer at home" types videos, but something that goes through the specifics of how a hardware qubit is built and how it operates with simplest use case possible.
