Quantum Barankin bounds beyond local unbiasedness: Analytic results for Gaussian states via a right-division framework
Maximilian Reichert, Javier Navarro, Gerardo Adesso +2
We propose a quantum version of the Barankin bound as an alternative to the quantum Cramér-Rao bound for quantum parameter estimation. The quantum Barankin bound provides a lower b…
Irreducible Architectures of Multipartite Entanglement
Augusto Smerzi, Manuel Gessner
Multipartite entanglement is commonly characterized by scalar notions such as separability and entanglement depth, which do not resolve the distribution of entangled cluster sizes.…
Quantum metrology with a continuous-variable system
Matteo Fadel, Noah Roux, Manuel Gessner
As one of the main pillars of quantum technologies, quantum metrology aims to improve measurement precision using techniques from quantum information. The two main strategies to ac…
Characterizing the Multipartite Entanglement Structure of Non-Gaussian Continuous-Variable States with a Single Evolution Operator
Mingsheng Tian, Xiaoting Gao, Boxuan Jing +4
Multipartite entanglement is an essential resource for quantum information tasks, but characterizing entanglement structures in continuous variable systems remains challenging, esp…
Fundamental bounds for parameter estimation with few measurements
Valentin Gebhart, Manuel Gessner, Augusto Smerzi
Bounding the optimal precision in parameter estimation tasks is of central importance for technological applications. In the regime of a small number of measurements, or that of lo…
Breaking local quantum speed limits with steering
Federico Centrone, Manuel Gessner
We show how quantum correlations allow us to break the local speed limits of physical processes using only local measurements and classical communication between two parties that s…
