Abstract
This paper explains the operation of a quantum Hadamard gate using photonic crystal structures. This is done by simulating a Y-junction beam-splitter in photonic crystal lattice. Normal modes in waveguides are used as qubits. Photonic crystals have been realized by stacking dielectric rods in air in the hexagonal lattice configuration. Index of substrate is chosen as 1.325 and angle of bend is 30°.
