Fundamental Limits in Mutiparameter Quantum Metrology

Abstract

We derive fundamental bounds on the maximal achievable precision in multiparameter noisy quantum channel estimation, as well as show operationally meaningful Heisenberg scaling precision limits for the multiple phase interferometry in the absence of noise.
