Method to determine which quantum operations can be realized with linear optics with a constructive implementation recipe
Garcia-Escartin, Juan Carlos; Gimeno, Vicent; Moyano-Fernández, Julio José American Physical Society (2019-08-02)The evolution of quantum light through linear optical devices can be described by the scattering matrix S of the system. For linear optical systems with m possible modes, the evolution of n input photons is given by a ... -
Optimal approximation to unitary quantum operators with linear optics
Garcia-Escartin, Juan Carlos; Gimeno, Vicent; Moyano-Fernández, Julio José Springer Nature (2021-09-21)Linear optical systems acting on photon number states produce many interesting evolutions, but cannot give all the allowed quantum operations on the input state. Using Toponogov’s theorem from differential geometry, we ...
