Web17 hours ago · Today, on 14 April, we celebrate World Quantum Day – an international initiative launched by scientists from more than 65 countries to promote public understanding of quantum science and technology worldwide. The date – “4.14” -- marks the rounded first 3 digits of Planck’s constant, a crucial value in quantum mechanics that is … 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.
