Why I started this blog

“Everything should be made as simple as possible, but not simpler.” (Albert Einstein)

When I first learned about quantum computing while preparing for my thesis, this was an issue. Having a brain that wants to understand things before applying them, I found myself lost in a sea of articles that were either too technical to grasp or too vague to be useful.

The technical articles used the math concepts I knew in a way that felt unnatural and hard to comprehend (What the heck is a Hilbert space anyway?!). Pop science articles, on the other hand, tend to throw around buzzwords without introducing or explaining them properly (Sure, entanglement sounds spooky, but how does that help us calculate faster?)

This blog is my attempt to find a middle ground.

My aim is to explain the basics in an approach that’s intuition first, math second, and fancy science talk last (or not at all). My goal is to enable anybody with a basic understanding of high school math and a decent interest in the topic to finally understand what the fuzz is all about.

That being said, most articles on this blog will focus on the fundamental questions I encountered when first learning about quantum computing, questions such as:

1. What can and what can’t a quantum computer do?
2. Why are quantum computers faster than classical computers on certain problems?
3. Where does the quantum advantage in f.e. Grover’s Algorithm come from?
4. …and many more.

While I do have experience in teaching, quantum computing, and writing, I am by no means an expert in any of these fields, let alone infallible.

If you have a question, ask.

If you notice a mistake, let me know so I can correct it and grow.
