Abstract: We investigate the application of weak measurement and measurement reversal scheme in Mach-Zehnder interferometer (MZI). By numerically simulating the experimental setup, we have found that the scheme can be implemented to recover the interferometric visibilities, as a measure of its effectiveness in combating amplitude damping decoherence. Our results demonstrate two suitable configurations that are able to improve the interferometer visibilities. Our results here are applicable to generic initial state and not limited to a specific initial photonic state. In addition, we extend our results to delayed-choice MZI and illustrate that the scheme of weak measurement and measurement reversal is also applicable in delayed-choice setups. Our simulations suggest that with increasing weak measurement parameter, we can recover the interferometric visibilities. Our results strongly suggest that the weak measurement and measurement reversal scheme is helpful in improving the visibilities of MZI and delayed-choice MZI with amplitude damping channel.
