Robust phase sensitivity in Mach-Zehnder interferometer using photon added and subtracted squeezed coherent state

arXiv:2607.02984v1 Announce Type: new Abstract: For the precision-based measurements, Mach-Zehnder interferometry is a widely used technique. There are various ways to enhance the precision of Mach-Zehnder interferometer (MZI), e.g., having a non-classical input state is one of the ways to enhance
