Abstract :
We propose two basic transformations which can be used for manipulating modal qubits in Ti:LiNbO3 photonic quantum circuits. These include the mode analyzer, a device that separates the even and odd components of a state into two separate spatial paths and a modal phase-flip gate which introduces a phase shift of π to the odd component of a two-mode photon state.
