Explicit formula of the separability criterion for continuous variables systems
Kazuo Fujikawa

TL;DR
This paper presents an explicit analytic formula for the separability criterion of two-party Gaussian systems in continuous variables, simplifying the process of determining entanglement.
Contribution
It introduces a new explicit formula for the separability criterion, improving upon previous formulations for continuous variable Gaussian systems.
Findings
The formula provides a clear criterion for separability.
Comparison shows the new formula is more explicit than past methods.
Facilitates easier entanglement detection in Gaussian systems.
Abstract
A very explicit analytic formula of the separability criterion of two-party Gaussian systems is given. This formula is compared to the past formulation of the separability criterion of continuous variables two-party Gaussian systems.
