Holevo Cramér-Rao bound: How close can we get without entangling measurements?
Aritra Das, Lorcán O. Conlon, Jun Suzuki +3
In multi-parameter quantum metrology, the resource of entanglement can lead to an increase in efficiency of the estimation process. Entanglement can be used in the state preparatio…
