Entangled Photon Generation in a Nonlinear Micro Ring Resonator for Quantum Key Distribution Use
In analysis of a new technique for quantum key distribution using the entangled photon within a micro ring resonator is presented. The Kerr nonlinear effects type of light circulates in the micro ring resonator is induced into the device. The superposition i.e. four-wave mixing of the propagating waves at resonance is occurred, where the entangled photon is generated. The possible two entangle pairs is described and discussed. The proposed system has shown the potential of using in the realistic system, where such a device scale can be fabricated and performed within the mobile telephone hand set, which means the use of quantum telephone will be realized in the near future.
