We theoretically study the phase sensitivity of an SU (1, 1) interferometer, in which the phase
shift is induced by a Kerr medium, together with a coherent state input and homodyne …

The usage of non-Gaussian states to improve the phase sensitivity of interferometers has
been studied before. In this paper, we introduce the multiphoton catalysis two-mode …

Interferometers are widely used as sensors in precision measurement. Compared with a
conventional Mach–Zehnder interferometer, the sensitivity of a correlation-enhanced …

The phase sensitivity of SU (1, 1) interferometer is investigated using a coherent state and
an m-coherent superposition squeezed vacuum states as inputs and the intensity detection …

We propose a theoretical scheme to improve the resolution and precision of phase
measurement with parity detection by using a nonclassical state generated by applying a …

This study investigates the use of orbital angular momentum (OAM) to enhance phase
estimation in Mach-Zehnder interferometers by employing non-Gaussian states as input …

The sensitivity of classical Raman spectroscopy methods, such as coherent anti-stokes
Raman spectroscopy (CARS) or stimulated Raman spectroscopy (SRS), is ultimately limited …

We propose a theoretical scheme of an enhanced phase sensitivity by introducing a
nonlinear phase shifter to the nonconventional interferometer consisting of a balanced beam …

We discuss how two-photon absorption (TPA) of squeezed and coherent states of light can
be detected in measurements of the transmitted light fields. Such measurements typically …

We present a new operator method in the Heisenberg representation to obtain the signal of
parity measurement within a lossless SU (1, 1) interferometer. Based on this method, it is …
