# Physics & Space

Exoplanets, quantum computing and fusion, from new measurements to bold simulations.

## Papers

- [Teaching a controller to tame a tokamak](https://papersays.com/p/teaching-a-controller-to-tame-a-tokamak): A fusion plasma can lose control in milliseconds. Can a learned controller keep it stable better than hand-tuned rules?
- [Error correction that gets better as it scales](https://papersays.com/p/error-correction-that-gets-better-as-it-scales): Adding more qubits usually adds more errors. This experiment shows a processor where the opposite happened, at least for now.
- [Hazy skies on small gas planets](https://papersays.com/p/hazy-skies-on-small-gas-planets): Thirty-eight planets between Earth and Neptune in size, and most seem to hide their atmospheres. What is getting in the way?
