Geometric obstructions to quadratic time scaling in multiparameter quantum estimation
Eoin O'Connor, Jiayu He, Matteo G. A. Paris +1
Unitary encoding of a single parameter provides quadratic enhancement in precision, with the quantum Fisher information scaling quadratically with the encoding time. However, when…
Bayesian stepwise estimation of qubit rotations
Mylenne Manrique, Marco Barbieri, Assunta Di Vizio +4
This work investigates Bayesian stepwise estimation (Se) for measuring the two parameters of a unitary qubit rotation. While asymptotic analysis predicts a precision advantage for…
Link prediction with swarms of chiral quantum walks
Gaia Forghieri, Viacheslav Dubovitskii, Matteo A. C. Rossi +1
Reconstructing protein-protein interaction networks is a central challenge in network medicine, often addressed using link prediction algorithms. Recent studies suggest that quantu…
Orders matter: tight bounds on the precision of sequential quantum estimation for multiparameter models
Gabriele Fazio, Jiayu He, Matteo G. A. Paris
In multiparameter quantum metrology, the ultimate precision of joint estimation is dictated by the Holevo Cramér-Rao bound. In this paper, we discuss and analyze in detail an alter…
Weight-dependent and weight-independent measures of quantum incompatibility in multiparameter estimation
Jiayu He, Gabriele Fazio, Matteo G. A. Paris
Multiparameter quantum estimation faces a fundamental challenge due to the inherent incompatibility of optimal measurements for different parameters, a direct consequence of quantu…
Enhanced quantum sensing of gravitational acceleration constant
Giorgio Stucchi, Matteo G. A. Paris
We investigate the use of quantum probes to accurately determine the strength of the local gravitational field on Earth. Our findings show that delocalized probes generally outperf…
Scrambling for precision: optimizing multiparameter qubit estimation in the face of sloppiness and incompatibility
Jiayu He, Matteo G. A. Paris
Multiparameter quantum estimation theory plays a crucial role in advancing quantum metrology. Recent studies focused on fundamental challenges such as enhancing precision in the pr…
From Staging to Insight: An Educational Path to Understanding Bell's Inequalities
Valentina De Renzi, Matteo G. A. Paris, Maria Bondani
Quantum Physics is a cornerstone of modern science and technology, yet a comprehensive approach to integrating it into school curricula and communicating its foundations to policym…
Cartan Quantum Metrology
Gabriele Fazio, Jiayu He, Matteo G. A. Paris
We address the characterization of two-qubit gates, focusing on bounds to precision in the joint estimation of the three parameters that define their Cartan decomposition. We deriv…
Are intrinsic decoherence models physical theories?
Maria Danelli, Matteo G. A. Paris
Intrinsic decoherence models (IDMs) have been proposed in order to solve the measurement problem in quantum mechanics. In this work, we assess the status of two of these models as…
