Abstract

Base on the definition of two-mode entangled coherent states,the relation of parameter and von Neumann entropy is studied.The results show that the μ,v and r all have some definitive affection on von Neumann entropy.When μ=-v and a smaller r,the von Neumann entropy is bigger,namely,entangled degree of the two parts of system is bigger.

On the relation between the shannon entropy and the von neumann entropy

Siu‐Wai Ho, Raymond W. Yeung

This paper presents three approaches to explore the relation between the Shannon entropy and the von Neumann entropy. The first two approaches are based on the measurement of the quantum state, while the third approach is based on the preparation of the quantum state. Each of these approaches leads to an alternative definition of the von Neumann entropy.

A von Neumann Entropy Measure of Entanglement Transfer in a Double Jaynes-Cummings Model

Samina Masood, Allen H. Miller

We study the entanglement in a system consisting of two non-interacting atoms located in separate cavities, both in their ground states. A single incoming photon has a non-zero probability of entering either of the two cavities. The Jaynes-Cummings interaction in the rotating wave approximation describes the coupling of each atom with the radiation field. We compute and analyze the atom-atom entanglement, the entanglement between the two photon modes, and also the entanglement between each atom and each photon mode. The measure of entanglement is the von Neumann entropy. For the case in which the two atom-photon systems have identical properties, but allowing for non-resonant conditions, the sum of the atom-atom and photon-modes-entanglement is time independent. The effect of detuning is to decrease the strength of the largest entanglement achieved and to shorten the time for it to occur. The results support the fact that the state of the photons after emergence from cavities is entangled, notwithstanding its single-particle nature. In addition, for the case of resonance and identical cavity parameters, we demonstrate that von Neumann entropy is always greater than or equal to the measure of entanglement known as negativity.

Entanglement of a two-level atom papered in a finite trio-coherent state

S. Abdel‐Khalek, Eied Mahmoud Khalil, S. I. Ali

In this paper, we study the interaction between an effective two-level atom and a three-mode field. The atom and the field are initially in the excited state and finite dimensional trio-coherent state, respectively. For this sytem, we investigate the atomic inversion, the von Neumann entropy, and the atomic Wehrl entropy. We show that there is a connection between all of these quantities. Also, we prove that the atomic Wehrl entropy exhibits a temporal evolution similar to the von Neumann entropy. It is observed that the Stark shift parameter plays an important role on the evolution of these quantities.

Evolution of field entropy and entanglement in the intensity-dependent two-mode Jaynes–Cummings model

Gao Yun-feng, Jian Feng, Ji‐Suo Wang

The evolution of the entanglement degree of two-mode fields and atom with the intensity-dependent coupling is investigated using von Neumann entropy. The results for the initial fields in both coherent states and two-mode squeezed vacuum state are calculated. The influence of the field intensity on the entropy is discussed. It is found that the field and atom are generally in maximum entanglement but subject to periodic pulsed disentanglement completely under the condition of strong initial field.

Von Neumann entropy in a dispersive cavity

Ram Narayan Deb

We study the von Neumann entropy of the partial trace of a system of 2 two-level atoms (qubits) in a dispersive cavity where the atoms are interacting collectively with a single-mode electromagnetic field in the cavity. We make a contrast of this entanglement entropy with the spin squeezing property of the system. We find a close relationship between this von Neumann entropy and the spin squeezing of the system. We observe that this entanglement entropy attains its maximum value when the spin squeezing in the system goes to its maximum and is zero when the spin squeezing in the system vanishes.

Evolution of decoherence in a two-mode entangled system under amplitude decay

Xiang-Guo Meng, Lian-Zhen Cao, Zhen-Shan Yang +1 more

Based on our recently published work [Front. Phys. 21, 093201 (2026)], we extend the analysis to the density-operator evolution of a two-mode entangled quantum system subject to amplitude decay and show that the output state retains the same functional structure as the initial density operator throughout the decay. We further examine the evolutions of several quantum statistical distributions and the von Neumann entropy used to quantify entanglement during the process. This work offers a systematic approach to studying two-mode entangled open systems and yields results on the von Neumann entropy that may help facilitate entanglement measurement.
