A protocol for global multiphase estimation
Giovanni Chesi, Roberto Rubboli, Alberto Riccardi +2
Global estimation strategies allow to extract information on a phase or a set of phases without any prior knowledge, which is, instead, required for local estimation strategies. We…
Quantum metrology of noisy spreading channels
Wojciech Górecki, Alberto Riccardi, Lorenzo Maccone
We provide the optimal measurement strategy for a class of noisy channels that reduce to the identity channel for a specific value of a parameter (spreading channels). We provide a…
Tight bounds from multiple-observable entropic uncertainty relations
Alberto Riccardi, Giovanni Chesi, Chiara Macchiavello +1
We investigate the additivity properties for both bipartite and multipartite systems by using entropic uncertainty relations (EUR) defined in terms of the joint Shannon entropy of…
Quantum thermodynamics of two bosonic systems
Chiara Macchiavello, Alberto Riccardi, Massimiliano F. Sacchi
We study the energy exchange between two bosonic systems that interact via bilinear transformations in the mode operators. The first mode is considered as the thermodynamic system,…
Technical Design Report for the PANDA Endcap Disc DIRC
Panda Collaboration, F. Davi, W. Erni +460
PANDA (anti-Proton ANnihiliation at DArmstadt) is planned to be one of the four main experiments at the future international accelerator complex FAIR (Facility for Antiproton and I…
Optimal entanglement witnesses from limited local measurements
Alberto Riccardi, Dariusz Chruściński, Chiara Macchiavello
We address the problem of optimising entanglement witnesses when a limited fixed set of local measurements can be performed on a bipartite system, thus providing a procedure, feasi…
Squeezing metrology: a unified framework
Lorenzo Maccone, Alberto Riccardi
Quantum metrology theory has up to now focused on the resolution gains obtainable thanks to the entanglement among N probes. Typically, a quadratic gain in resolution is achievable…
State independent uncertainty relations from eigenvalue minimization
Paolo Giorda, Lorenzo Maccone, Alberto Riccardi
We consider uncertainty relations that give lower bounds to the sum of variances. Finding such lower bounds is typically complicated, and efficient procedures are known only for a…
Multipartite steering inequalities based on entropic uncertainty relations
Alberto Riccardi, Chiara Macchiavello, Lorenzo Maccone
We investigate quantum steering for multipartite systems by using entropic uncertainty relations. We introduce entropic steering inequalities whose violation certifies the presence…
Tripartite entanglement detection through tripartite quantum steering in one-sided and two-sided device-independent scenarios
C. Jebaratnam, Debarshi Das, Arup Roy +5
In the present work, we study tripartite quantum steering of quantum correlations arising from two local dichotomic measurements on each side in the two types of partially device-i…
Tight entropic uncertainty relations for systems with dimension three to five
Alberto Riccardi, Chiara Macchiavello, Lorenzo Maccone
We consider two (natural) families of observables for systems with dimension : the spin observables , and , and the observables that have mutually un…
Feasibility study for the measurement of TDAs at PANDA in
PANDA Collaboration, B. Singh, W. Erni +508
The exclusive charmonium production process in annihilation with an associated meson is studied in the framework of QCD collinear factorizatio…
