Symmetric tensor product

WebIt follows that the basis of any symmetric tensor D has six elements, so the set of all symmetric tensors is a six-dimensional inner product space ε 6. Note that only six … WebIn this article, we derive a closed form expression for the symmetric logarithmic derivative of Fermionic Gaussian states. This provides a direct way of computing the quantum Fisher Information for Fermionic Gaussian states. Applications range from quantum Metrology with thermal states to non-equilibrium steady states with Fermionic many-body systems.
