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

Notes

D. Gómez Aguado has been supported by the Spanish Government (Ministerio de Educación y Formación Profesional, Beca de Colaboración en Departamentos Universitarios).
