Transverse modes of optical waveguide are proposed to be encoded as qubits for the implementation of a quantum NOT gate. To realize a quantum NOT gate Mach-Zehnder Interferometer (MZI) with a phase shifter are utilized. The possibility of this encoding scheme was designed, simulated and verified through rigorous numerical analyses using the Beam propagation method (BPM). The proposed gate has the potential of being more compact and easily realizable than some other optical implementation proposals. The Results showed that the designed model was a successful implementation of a quantum NOT gate.
