Symmetric Logarithmic Derivative of Fermionic Gaussian States
Angelo Carollo, Bernardo Spagnolo, Davide Valenti
In 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…
On quantumness in multi-parameter quantum estimation
Angelo Carollo, Bernardo Spagnolo, Alexander A. Dubkov +1
In this article we derive a measure of quantumness in quantum multi-parameter estimation problems. We can show that the ratio between the mean Uhlmann Curvature and the Fisher Info…
Geometry of quantum phase transitions
Angelo Carollo, Davide Valenti, Bernardo Spagnolo
In this article we provide a review of geometrical methods employed in the analysis of quantum phase transitions and non-equilibrium dissipative phase transitions. After a pedagogi…
