Secured Data Communication by Using Quantum Entanglement of Photon between two nodes

Abstract

Quantum entanglement is the effective way to communicate with distant object in a wireless manner than the conventional way of communication techniques. In our proposed system we used split high energy photon which is parted into two equal valued photons. These photons will be entangled in nature which means they share the same spatial proximity. According to the quantum mechanics the changes that occur in one qubit photon will affect the changes in other qubit photon placed in far distance. This property of entanglement made quantum particle effective alternative for wireless communication. In our proposed technique qubits are formed by passing high power monochromatic laser beam into polarized potassium titanyl phosphate (KTP) crystal. The crystal will separate the input beam into two entangled qubits. These qubits are then captured in separate optical cavity with carbon nano tube. The wavelength of the individual photons can be changed with the help of varying photon wavelength converter. This can be detected at the receiver end photon. This change in wavelength can then be converted into electrical pulses which are then converted into digital signals with the help of Analog to Digital Converters (ADC). These above mentioned techniques are experimented below and the obtained results are compared with existing wireless communication approaches.
