# cl-quantum # cl-quantum
This is just some experiments with quantum computing emulation that I am doing `cl-quantum` is a quantum circuit simulator for common lisp. It also has a basic
for a school project. vector and matrix algebra library included. `cl-quantum` has external
requirements to use the main simulator, however, `cl-ppcre` is required to parse
back pretty-printed states. `cl-quantum` has been tested with SBCL 2.4.9 on
ArchLinux and was able to perform a simple Grover's search algorithm with 11
qbits in about 5 minutes.
I wrote this for a final project for my PHYSICS-103 class a LACC.
