AB Linear optical systems acting on photon number states produce many interesting evolutions, but cannot give all the allowed quantum operations on the input state. UsingToponogov’s theorem from differential geometry, we propose an iterative methodthat, for any arbitrary quantum operator U acting on n photons in m modes, returns anoperator Ũ which can be implemented with linear optics. The approximation methodis locally optimal and converges. The resulting operator Ũ can be translated into anexperimental optical setup using previous results.
