Kassiopeia VS QCSim

If you have any interest in single-particle tracking for ion optics. I'd encourage you to check out https://github.com/KATRIN-Experiment/Kassiopeia. It can do both exact and adiabatic tracking of particles (and will solve for B and E-fields in complex electrode geometries). However, as far as I know it only handles static electric fields for now.

This simulation was performed with our particle-tracking software Kassiopeia which contains a field calculation module. The streamlines and the moving surface are colored by electric potential; the other surfaces colors (bunny and surrounding box) represent the local charge density; and the streamlines follow the electric field.

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
