Abstract
This study investigates the effect of noise on two qubit quantum teleportation through a four qubit channel theoretically. Therefore, in this study a comparison of two states of teleportation through ideal and noisy channel was carried out. The noisy channel can have the effect of bit-flip channel and phase-flip channel. From these two effects, it is found that the fidelity depends on the noise factor (p) and the sent state constant. If the noise factor is neglected, then the fidelity value is 1. This indicates that the teleportation was successfully sent and at the same time confirms the teleportation behavior through ideal conditions. In this research, we varied three coefficient for the sent state, namely c00 = c01 = c10, with values of 0.250, 0.125, 0.0625. For the bit flip noise, we observed that as the values of the coefficient values of transmitted state increase, the fidelity value increases. Meanwhile, for the phase flip noise, we observed that as the values of the coefficient values of transmitted state increase, the fidelity value decreases.
