Windowed Catodyne Measurements: Continuum Approximation versus Exact Discrete Photon-Number Treatment
Elahe Nahvifard, Mohammad Reza Bazrafkan
We analyze a family of measurements obtained by retaining only a finite window of the photon-sum variable in catodyne detection, where a Schrödinger cat state serves as the local o…

Deriving Some Quantum Optical Identities Using the General Ordering Theorem
F. Shähandeh, M. R. Bazrafkan, E. Nahvifard
Using the newly introduced general ordering theorem (GOT) by Shähandeh and Bazrafkan, we derive and generalize some quantum optical identities and give their applications.

Combinatorial Approach to Boson Anti-Normal Ordering Problem
M. R. Bazrafkan, F. Shähandeh, E. Nahvifard
We address a systematic combinatorial approach to the anti-normal ordering problem. In this way, we use the Stirling numbers and their generating function, the so-called Bell polyn…
