Attainability of the Holevo-Cramér-Rao bound for two-qubit 3D magnetometry
Jamie Friel, Pantita Palittapongarnpim, Francesco Albarelli +1
We study quantum-limited 3D magnetometry using two qubits. Two qubits form the smallest multi-qubit system for 3D magnetometry, the simultaneous estimation of three phases, as it i…

Evaluating the Holevo Cramér-Rao bound for multi-parameter quantum metrology
Francesco Albarelli, Jamie F. Friel, Animesh Datta
Only with the simultaneous estimation of multiple parameters are the quantum aspects of metrology fully revealed. This is due to the incompatibility of observables. The fundamental…
