# A little bit of LaTeX

Posted on

I’ve been busy watching videos. A lot of them, as part of my learning process for quantum computing. To concretize my learning, I’ve been taking notes. As quantum computing is hardcore math, it’s impossible to not have some sort of equations in notes. I’ve never needed to learn or use LaTeX before: all simple algebraic equations can be written in plain text using some jugaad, say using superscripts for exponentials. But how do you represent column vectors and matrices? That’s where LaTeX comes super-handy. As I’m using it more, the more fun it gets.

Auto-LaTeX Equations is an excellent add-on for Google Docs that makes it super-easy to write LaTeX code and convert it into good-quality images of math stuff and equations.

An example LaTeX render from my notes is this matrix that represents the phase shift quantum gate:
