AB - In this paper, a quantum scheme for a two-qubit system (2QS) and field  initially prepared in the excited negative binomial distribution is  presented. The field photon statistics is detected from the evolution of  the Mandel parameter, while the evolution of von Neumann entropy detects the  nonlocal correlation between the 2QS and radiation field. The concurrence is  used to detect the qubit-qubit entanglement during the time evolution. The  dynamical properties of single-qubit and two-qubit quantum Fisher  information are investigated. We visualize the number of photon excitations  on the field in negative binomial states with influence of photon success  probability. A connection is provided between the dynamical behaviors of  these statistical quantities. We have found that the proposed quantities are  strongly influenced by the number of excited photons of the field in  negative binomial states and photon success probability.
