Quantum Polarization in Two-Mode Generalized Binomial State

This study investigates quantum polarization in a two-mode generalized binomial state (TMGBS), a non-classical property of light, using quantum Stokes parameters and crucial in terms of its relationship to the purity and coherence of quantum states. Here we explore the criterion of quantum polarization in a generalized binomial state of light, which features a binomial photon number distribution in light pulses. Previous work by our group has examined other higher-order nonclassicality in single-and two-mode systems of GBS. Here we focus on the degree of polarization, an essential factor for observing entanglement in two-mode quantum states. Our findings emphasize the role of quantum polarization in detecting entanglement between optical modes, a fundamental resource for quantum communication protocols, including quantum teleportation and cryptography. The study demonstrates that TMGBS is an optimal candidate for achieving high degrees of quantum polarization under varied parameters, providing insights that could advance quantum technologies like quantum communication and metrology, where entanglement is pivotal.
