Optimal phase sensitivity of an unbalanced Mach-Zehnder interferometer
Karunesh K. Mishra, Stefan Ataman
In this paper we address the problem of optimizing an unbalanced Mach-Zehnder interferometer, for a given pure input state and considering a specific detection scheme. While the op…
Quantum Fisher information maximization in an unbalanced interferometer
Stefan Ataman
In this paper we provide the answer to the following question: given an arbitrary pure input state and a general, unbalanced, Mach-Zehnder interferometer, what transmission coeffic…
Single- versus two-parameter Fisher information in quantum interferometry
Stefan Ataman
In this paper we reconsider the single parameter quantum Fisher information (QFI) and compare it with the two-parameter one. We find simple relations connecting the single paramete…
Optimal Mach-Zehnder phase sensitivity with Gaussian states
Stefan Ataman
We address in this work the phase sensitivity of a Mach-Zehnder interferometer with Gaussian input states. A squeezed-coherent plus squeezed vacuum input state allows us to unambig…
