Introduction

Quantum computing is exciting. It has some sci-fi wibe with its multi-world theory, entanglement, anticasuality and other mystical words. Also it promises the solution and elimination of the whole NP problem class. Lots of people start to learn quantum computing just to hit a wall somewhere between the second and third lessons, where complex numbers, matrix transformations and complex physical phenomena come in the picture. In this blog, I will document my own path of understand and learn the quantum computing from the basics of Q-bits to the solution of fast number factorization.

I am an experienced IT engineer with slightly above average knowledge about physics and mathematics. If you have similar background and you want to learn the basics of the quantum computing, maybe this blog will be useful and interesting for you.

In my opinion (and experience), if somebody wants to understand quantum computing, they must forget everything they've heard about it. There are so many half truth or false information about this topic, that our own preconceptions will be our biggest enemies.
