Nonclassicality of multi-photon-added cat states
Jhordan Santiago, Petr Steindl
Multi-photon-added cat states are constructed by repeatedly applying the creation operator to a cat state. We study in detail their photon-number distribution, parameter, squee…

Higher-order nonclassicality criteria for photon-subtracted and photon-added states via the normalization constant
Jhordan Santiago
We show that any nonclassicality criterion based on factorial moments, including several higher-order parameters such as the Mandel parameter, the Lee antibunching fun…

Photon Statistics for Fock and Coherent States Interfering in a Beamsplitter
Jhordan A. T. Santiago
We present a straightforward yet comprehensive theoretical study of different quantum states emerging from a bi-modal beamsplitter when various input states interfere. Specifically…
