Description
QOptCraft is a Python package for the design and study of linear optical quantum systems. Functions include:
- Reck and Clemens optical decomposition of unitaries.
- Unitary approximation with linear optics using Toponogov's theorem
- Photonic homomorphism to quantize linear optical interferometers
- Recover, if possible, the linear optical scattering matrix from a unitary operator
- Create pure and mixed states in a handy way
- Calculate photonic invariants of states
