Mixed-state certification of quantum capacities for noisy communication channels

Chiara Macchiavello, Massimiliano F. Sacchi

We extend a recent method to detect lower bounds to the quantum capacity of quantum communication channels by considering realistic scenarios with general input probe states and ar…

Detection of properties and capacities of quantum channels

Chiara Macchiavello, Massimiliano F. Sacchi

We review in a unified way a recently proposed method to detect properties of unknown quantum channels and lower bounds to quantum capacities, without resorting to full quantum pro…

The Thirring quantum cellular automaton

A. Bisio, G. M. D'Ariano, P. Perinotti +1

We analytically diagonalize a discrete-time on-site interacting fermionic cellular automaton in the two-particle sector. Important features of the solutions sensibly differ from th…

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…

Quantum Time: experimental multi-time correlations

Ekaterina Moreva, Marco Gramegna, Giorgio Brida +2

In this paper we provide an experimental illustration of Page and Wootters' quantum time mechanism that is able to describe two-time quantum correlation functions. This allows us t…

Localized Thermal States

Fausto Borgonovi, Felix M. Izrailev

It is believed that thermalization in closed systems of interacting particles can occur only when the eigenstates are fully delocalized and chaotic in the preferential (unperturbed…

Isotropic quantum walks on lattices and the Weyl equation

Giacomo Mauro D'Ariano, Marco Erba, Paolo Perinotti

We present a thorough classification of the isotropic quantum walks on lattices of dimension for cell dimension . For there exist two isotropic walks, namely t…

Experimental ancilla-assisted phase-estimation in a noisy channel

Marco Sbroscia, Ilaria Gianani, Luca Mancino +5

The metrological ability of carefully designed probes can be spoilt by the presence of noisy processes occurring during their evolution. The noise is responsible for altering the e…

Quantum Walks, Weyl equation and the Lorentz group

Alessandro Bisio, Giacomo Mauro D'Ariano, Paolo Perinotti

Quantum cellular automata and quantum walks provide a framework for the foundations of quantum field theory, since the equations of motion of free relativistic quantum fields can b…

Cryptographic quantum metrology

Zixin Huang, Chiara Macchiavello, Lorenzo Maccone

We develop a general framework for parameter estimation that allows only trusted parties to access the result and achieves optimal precision. The protocols are designed such that a…

The Pauli objection

Juan Leon, Lorenzo Maccone

Schroedinger's equation says that the Hamiltonian is the generator of time translations. This seems to imply that any reasonable definition of time operator must be conjugate to th…

Path-sum solution of the Weyl Quantum Walk in 3+1 dimensions

Giacomo Mauro D'Ariano, Nicola Mosco, Paolo Perinotti +1

We consider the Weyl quantum walk in 3+1 dimensions, that is a discrete-time walk describing a particle with two internal degrees of freedom moving on a Cayley graph of the group $…

Digital Quantum Estimation

Lorenzo Maccone, Majid Hassani, Chiara Macchiavello

Quantum Metrology calculates the ultimate precision of all estimation strategies, measuring what is their root mean-square error (RMSE) and their Fisher information. Here, instead,…

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…

Multipartite entanglement detection for hypergraph states

Maddalena Ghio, Daniele Malpetti, Matteo Rossi +2

We study the entanglement properties of quantum hypergraph states of qubits, focusing on multipartite entanglement. We compute multipartite entanglement for hypergraph states w…

Multipartite correlations in mutually unbiased bases

David Sauerwein, Chiara Macchiavello, Lorenzo Maccone +1

We introduce new measures of multipartite quantum correlations based on classical correlations in mutually unbiased bases. These classical correlations are measured in terms of the…

Physics Without Physics: The Power of Information-theoretical Principles

Giacomo Mauro D'Ariano

David Finkelstein was very fond of the new information-theoretic paradigm of physics advocated by John Archibald Wheeler and Richard Feynman. Only recently, however, the paradigm h…

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…
