Zero–trade-off multiparameter quantum estimation via simultaneously saturating multiple Heisenberg uncertainty relations
Quantum estimation of a single parameter has been studied extensively. Practical applications, however, typically involve multiple parameters, for which the ultimate precision is much less understood. Here, by relating the precision limit directly to the Heisenberg uncertainty relation, we show that...
