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…
Experimental quantum-enhanced response function estimation
Ilaria Gianani, Francesco Albarelli, Valeria Cimini +1
Characterizing a system often demands learning its response function to an applied field. Such knowledge is rooted on the experimental evaluation of punctual fiducial response and…
Noisy quantum metrology enhanced by continuous nondemolition measurement
Matteo A. C. Rossi, Francesco Albarelli, Dario Tamascelli +1
We show that continuous quantum nondemolition (QND) measurement of an atomic ensemble is able to improve the precision of frequency estimation even in the presence of independent d…
Time-local optimal control for parameter estimation in the Gaussian regime
Alexander Predko, Francesco Albarelli, Alessio Serafini
Information about a classical parameter encoded in a quantum state can only decrease if the state undergoes a non-unitary evolution, arising from the interaction with an environmen…
A perspective on multiparameter quantum metrology: from theoretical tools to applications in quantum imaging
Francesco Albarelli, Marco Barbieri, Marco G. Genoni +1
The interest in a system often resides in the interplay among different parameters governing its evolution. It is thus often required to access many of them at once for a complete…
Upper bounds on the Holevo Cramér-Rao bound for multiparameter quantum parametric and semiparametric estimation
Francesco Albarelli, Mankei Tsang, Animesh Datta
We formulate multiparameter quantum estimation in the parametric and semiparametric setting. While the Holevo Cramér-Rao bound (CRB) requires no substantial modifications in moving…
