It might be a good time to learn some basics of SC, huh?

Conceptually there is nothing special or impossible about room temperature or much higher temperature superconductors except they have not been decisively observed. After all ferromagnets exist with high Curie temperatures ~ 1400 F (Fe), 2100 F (Co), and we take them as given!

Last weekend, I finished my first half Marathon race! Finished in 1h40m and ranked 173rd of 1382. Although I could not break my PR, I’m really proud of the effort!

It actually makes a lot of sense. A company called _MagicHub_ could be the next unicorn lol.

You laugh but you could totally imagine "T gate farms" that beam magic states to other quantum computers on a quantum internet network

Hidden Inverses: Coherent Error Cancellation at the Circuit Level

Coherent gate errors are a concern in many proposed quantum-computing architectures. Here, we show that certain coherent errors can be reduced by a local optimization that chooses between two forms...
