Modifications to qubit simulation code

[Rick Muller]

I was planning to jump into the Sympy quantum stuff a bit more, and wanted to make sure I wouldn’t be stepping on anyone’s toes.

 

Here’s what I have in mind:

1. Expand sympy/physics/quantum documentation for qubit circuits and simulations. At one point a while back I wrote a ipython notebook on using sympy circuit diagrams, but this mostly amounts to my test cases. I’d like to write a guide along the lines of the Quipper programming guide (arXiv:1304.5485), but using Sympy tools. A lot of this is already in Sympy, and my writing more in-depth documentation will be a good way to remind myself what works and what still needs to be added.
   
2. When I worked on this a long time ago, the circuit simulators were very inefficient – they essentially created full matrices for every operation, if I remember correctly. I have a working vector state simulator for arbitrary quantum states that I could reimplement in Sympy pretty easily. This would give Sympy functionality that would be pretty close to what’s in Quipper.
3. Time permitting, it would be nice to do a stabilizer solver. Aaronson’s site already has the code.

 

Anyone have any objections, or alternate suggestions?

Rick,

Go for it. Noone has touched that code in years.
