Uncertainty, von Neumann Entropy, and Squeezing in a Bipartite State of Two-Level Atoms
Ram Narayan Deb
We provide a generalized treatment of uncertainties, von Neumann entropy, and squeezing in entangled bipartite pure state of two-level atoms. We observe that when the bipartite sta…
Von Neumann entropy in a dispersive cavity
Ram Narayan Deb
We study the von Neumann entropy of the partial trace of a system of two two-level atoms (qubits) in a dispersive cavity where the atoms are interacting collectively with a single…
Von Neumann Entropy from Mean Spin Vector
Ram Narayan Deb
We show for a general pure entangled state of two two-level atoms, the von Neumann entropy of the partial traces can be directly measured from the magnitude of the mean spin vector…
Measure of tripartite quantum correlation in multiqubit symmetric pure state
Ram Narayan Deb
We propose a direct measure of tripartite quantum correlation in an arbitrary symmetric pure state of N correlated two-level atoms (qubits). We compute the third order moments of t…
A total measure of multi-particle quantum correlations in atomic Schrödinger cat states
Ram Narayan Deb
We propose a total measure of multi-particle quantum correlation in a system of N two-level atoms (N qubits). We construct a parameter that encompasses all possible quantum correla…
Quantification of Quantum Entanglement in a Multiparticle System of Two-Level Atoms Interacting with a Squeezed Vacuum State of the Radiation Field
Ram Narayan Deb
We quantify multiparticle quantum entanglement in a system of N two-level atoms interacting with a squeezed vacuum state of the electromagnetic field. We calculate the amount of qu…
