CONTINUOUS MODE ANALYSIS OF TOOLS FOR QUANTUM TELEPORTATION

Abstract

We study continuous mode model of photon state. We also study the models of photo detectors. We develop the continuous mode model for real world photon detectors which consider the effects of variation in efficiency of detector depending upon its spectral function. We study the nature of entanglement in different Bell states and develop continuous mode form of Bell states. We verify the behavior of Bell states by finding the coincidence between detec tors acting as Bell state analyzers. Entanglement is the phenomenon which plays key role in teleportation. Once we varify that nature of entanglement remains preserved in our continuous mode model of Bell state, we teleport an unknown continuous mode state using our continuous mode model of photon states and photo detectors. We calculate the three-fold coincidence among four detectors while two detectors act as Bell state analyzers and other two are used for detection of teleported state. We find that three-fold coincidence probability curves are in accordance with expected values.
