Exact and approximate solutions for the quantum minimum-Kullback-entropy estimation problem
Carlo Sparaciari, Stefano Olivares, Francesco Ticozzi +1
The minimum Kullback entropy principle (mKE) is a useful tool to estimate quantum states and operations from incomplete data and prior information. In general, the solution of a mK…
Extending robustness & randomization from Consensus to Symmetrization Algorithms
Luca Mazzarella, Francesco Ticozzi, Alain Sarlette
This work interprets and generalizes consensus-type algorithms as switching dynamics leading to symmetrization of some vector variables with respect to the actions of a finite grou…
Optimal Binary Codes and Measurements for Classical Communication over Qubit Channels
Nicola Dalla Pozza, Nicola Laurenti, Francesco Ticozzi
We propose constructive approaches for the optimization of binary classical communication over a general noisy qubit quantum channel, for both the error probability and the classic…
Steady-State Entanglement by Engineered Quasi-Local Markovian Dissipation
Francesco Ticozzi, Lorenza Viola
We characterize and construct time-independent Markovian dynamics that drive a finite-dimensional multipartite quantum system into a target (pure) entangled steady state, subject t…
Consensus for Quantum Networks: From Symmetry to Gossip Iterations
Luca Mazzarella, Alain Sarlette, Francesco Ticozzi
This paper extends the consensus framework, widely studied in the literature on distributed computing and control algorithms, to networks of quantum systems. We define consensus si…
Minimum Relative Entropy for Quantum Estimation: Feasibility and General Solution
Mattia Zorzi, Francesco Ticozzi, Augusto Ferrante
We propose a general framework for solving quantum state estimation problems using the minimum relative entropy criterion. A convex optimization approach allows us to decide the fe…
