The Differential Entropy of the Joint Distribution of Eigenvalues of Random Density Matrices

The Differential Entropy of the Joint Distribution of Eigenvalues of Random Density Matrices

We derive exactly the differential entropy of the joint distribution of eigenvalues of Wishart matrices. Based on this result, we calculate the differential entropy of the joint distribution of eigenvalues of random mixed quantum states, which is induced by taking the partial trace over the environm...
