We design optimal interferometric schemes for implementation of two-qubit linear optical quantum filters diagonal in the computational basis. The filtering is realized by interference two photons encoding qubits a multiport interferometer, followed conditioning on presence single photon each output port filter. filter thus operates coincidence basis, similarly to many unitary gates. Implementat...

It is shown that the Lorentz group plays prominent roles in at least two areas in condensed matter physics, namely in the Bogoliubov transformation and optical filters. It is pointed out that the underlying symmetry of the Bogoli-ubov transformation is that of two coupled oscillators, and that the underlying symmetry of two coupled oscillators in that of the group O(3, 3). The Lorentz group is ...
