TL;DR

This paper investigates the bounds of D-concurrence, a new entanglement measure, for pair coherent states, which are non-Gaussian states of a two-mode radiation field, providing theoretical insights into their entanglement properties.

Contribution

The paper derives and calculates the upper and lower bounds of D-concurrence for pair coherent states, advancing understanding of their entanglement characteristics.

Findings

Bounds for D-concurrence are established for pair coherent states.

The study provides analytical calculations of these bounds.

Results contribute to the theoretical understanding of non-Gaussian entangled states.

Abstract

The pair coherent state is a state of a two-mode radiation field which is known as a state with non-Gaussian wave function. In this paper, the upper and lower bounds for D-concurrence (a new entanglement measure) have been studied over this state and calculated.
