Linear optics only allows every possible quantum operation for one photon or one port
Moyano-Fernández, Julio José; García-Escartín, Juan Carlos Elsevier (2017)We study the evolution of the quantum state of n photons in m different modes when they go through a lossless linear optical system. We show that there are quantum evolution operators U that cannot be built with linear ... -
Method to determine which quantum operations can be realized with linear optics with a constructive implementation recipe
García-Escartín, Juan Carlos; Gimeno, Vicent; Moyano-Fernández, Julio José American Physical Society (2019)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 ... -
Multiple photon effective Hamiltonians in linear quantum optical networks
García-Escartín, Juan Carlos; Gimeno, Vicent; Moyano-Fernández, Julio José Elsevier (2019)We give an alternative derivation for the explicit formula of the effective Hamiltonian describing the evolution of the quantum state of any number of photons entering a linear optics multiport. The description is based ...
