Quantumness of gravitational cat states in correlated dephasing channels
Saeed Haddadi, Mehrdad Ghominejad, Artur Czerwinski
We study the quantumness of gravitational cat states in correlated dephasing channels. Our focus is on exploring how classical correlations between successive actions of a dephasin…

A comparative study of LQU and LQFI in general qubit-qutrit axially symmetric states
M. A. Yurischev, Saeed Haddadi, Mehrdad Ghominejad
We derive the compact closed forms of local quantum uncertainty (LQU) and local quantum Fisher information (LQFI) for hybrid qubit-qutrit axially symmetric (AS) states. This allows…

Quantum dense coding with gravitational cat states
Saeed Haddadi, Mehrdad Ghominejad, Artur Czerwinski
A protocol of quantum dense coding with gravitational cat states is proposed. We explore the effects of temperature and system parameters on the dense coding capacity and provide a…
