QCSim VS SolarSystem

I implemented one myself, just for fun: https://github.com/aromanro/QCSim I intend to extend/improve it further. For somebody that knows C++ maybe it's worth checking out.

Just for fun, since you are a software engineer, do what I did while you go over that book: implement a quantum computer simulator (here it is mine: https://github.com/aromanro/QCSim).

If beginner, get this: https://www.cambridge.org/highereducation/books/quantum-computation-and-quantum-information/01E10196D0A682A6AEFFEA52D53BE9AE#overview go over it and if you can implement a quantum computing simulator afterwards (it's easy, here is one I implemented: https://github.com/aromanro/QCSim), you probably can take an informed decision.

I can think of only two things that might appear a little bit more complex: partial measurement of the register and extending the operators to be applied on the register, otherwise it's quite straightforward. I added some notes in the README for the project describing the code a little: https://github.com/aromanro/QCSim

I implemented that here: https://github.com/aromanro/QCSim/blob/master/QCSim/ShorCode.h part of this project: https://github.com/aromanro/QCSim

Here is the code again: https://github.com/aromanro/QCSim just in case you don't see my other comment.

That's what I did: https://github.com/aromanro/QCSim

I also ported it in an opengl project: https://github.com/aromanro/SolarSystem

I've got a lot of physics-related projects on GitHub, most of them use matrices, even if sometimes it's not obvious. For example, this one: https://github.com/aromanro/SolarSystem uses matrices for changing from one coordinate system to another, rotations and so on.

I also have a solar system simulator, it used at first velocity Verlet, then I switched to Verlet since I really didn't need the velocity in it: https://github.com/aromanro/SolarSystem

There are countless of open source programs that do that, you just have to look over the sources. For example, one of my projects: aromanro/SolarSystem: A solar system simulator with velocity Verlet, using OpenGL for displaying. (github.com)
