We prove that the log-determinant of the covariance matrix obeys the strong subadditivity inequality for arbitrary tripartite states of multimode continuous variable quantum systems. This establishes general limitations on the distribution of informa... Read More about Strong subadditivity for log-determinant of covariance matrices and its applications.
