Slow blogging + a couple of articles

Sorry - blogging has been slow in recent days because, despite it being summer, it's been a very busy time for various reasons.

Here are a couple of articles that I've come across that seem interesting.  On the news/popular writing front:

• The Hubble Space Telescope isn't dead yet!
• TSMC is going to crank up fab capacity for the older generation (e.g. 28 nm node) chips that do important things like run our cars.
• Intel might be trying to buy GlobalFoundries (the fab arm spun off by AMD a while ago).
• A great article by Natalie Wolchover about progress in pure math circles regarding relative sizes of infinities.

On the science front, there have been several cool things that I haven't had time to look at in depth.  A couple of quantum info papers:

• In this Nature paper, the google quantum AI team have used their 53 qubit chip to do proof-of-concept demonstrations of two different quantum error correction approaches.  Perhaps someone more knowledgable that me can chime in below in the comments about how the ratio of physical qubits to logical qubits depends on the fidelity and other properties of the physical qubits.  Basically, I'm wondering if, e.g., ion trap-based schemes would be able to make even better advantage out of the 1D error correction approach here.
• Meanwhile, in China a large group has demonstrated a 66 qubit system similar in design to the google/Martinis approach.
