An approach to realize a quantum NOT gate through optical implementation

Transverse modes of electromagnetic fields are proposed to be encoded as qubits for the implementation of a quantum NOT gate. The possibility of this encoding scheme was designed, simulated and verified through rigorous numerical analyses using the Beam propagation method. The proposed gate has the potential of being more compact and easily realizable than some other optical implementation proposals since it is based on planar light wave circuit technology and can be constructed very easily by using a planar light wave technology. The Results proved that the design is able to perform the required NOT transformation and the conclusion was reached that the model was a successful implementation of a quantum NOT gate.
