The phase-sensitivity of a Mach–Zehnder interferometer for Fock state inputs
TL;DR: In this paper, the phase-sensitivity of some different measurement schemes with a Mach-Zehnder interferometer is studied, where the input light is considered to be in a photon number state and the detectors are assumed to be ideal with quantum efficiency of unity.

The Phase-sensitivity of a Mach-Zehnder Interferometer for Coherent Light
TL;DR: In this paper, the sensitivity of four different phase shift measurement schemes with a Mach-Zehnder interferometer has been studied, and it has been shown that the uncertainty of the phase-shift measurement is limited to the classical 1/m −1/m (m is the average number of photons in the input state).

The Relation between Statistics of Input Photons and Photocounts
TL;DR: The relation between the statistics of photons in input light on a detector and the measured photocounts by the detector is discussed in this paper, where the average and variances of the photocount are compared with the averages and variance of input photons on practical detectors having quantum efficiencies of $\mu$.

TL;DR: In this article, the relation between the statistics of photons in input light on a detector and the measured photocounts is discussed for two types of light measurement, i.e., single photocount with one detector and coincidence detection with two detectors.

Effect of the detector efficiency on the phase sensitivity in a mach-zehnder interferometer
TL;DR: In this paper, the effect of quantum efficiencies of detectors on the phase sensitivity of a Mach-Zehnder was analyzed for the Fock state input, and the phase uncertainty of two different interference experiments, the second-order and the fourth-order, were compared with two practical detectors with less than unit quantum efficiency.
