Incompatibility in Multi-Parameter Quantum Metrology with Fermionic Gaussian States

In this article we derive a closed form expression for the incompatibility condition in multi-parameter quantum metrology when the reference states are Fermionic Gaussian states. Together with the quantum Fisher information, the knowledge of the compatibility condition provides a way of designing op...
