Linear optics only allows every possible quantum operation for one photon or one port
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 ... -
Multiple photon effective Hamiltonians in linear quantum optical networks
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 ...

No-go theorems for photon state transformations in quantum linear optics
Elsevier (2023)We give a necessary condition for photon state transformations in linear optical setups preserving the total number of photons. From an analysis of the algebra describing the quantum evolution, we find a conserved quantity ...
