Quantum States and Hardy's Formulation of the Uncertainty Principle : a Symplectic Approach
Maurice de Gosson, Franz Luef
We express the condition for a phase space Gaussian to be the Wigner distribution of a mixed quantum state in terms of the symplectic capacity of the associated Wigner ellipsoid. O…

Remarks on the Fact that the Uncertainty Principle Does Not Determine the Quantum State
Maurice de Gosson, Franz Luef
We discuss the relation between density matrices and the uncertainty principle; this allows us to justify and explain a recent statement by Man'ko et al. We thereafter use Hardy's…
