Optical Fiber Communication Using Quantum Teleportation

Niranjan Behera EI200127113 [3]

With the advent of fiber optics, data can be very

easily and rapidly transmitted over long distances.In optical fiber, light is used for propagation of

data.

Total Internal Reflection

Need for better speed and perfectly secure
