Experimental detection of quantum channel capacities

Álvaro Cuevas, Massimiliano Proietti, Mario Arnolfo Ciampini +4

We present an effcient experimental procedure that certifies non vanishing quantum capacities for qubit noisy channels. Our method is based on the use of a fixed bipartite entangle…

Multi-partite entanglement speeds up quantum key distribution in networks

Michael Epping, Hermann Kampermann, Chiara Macchiavello +1

The laws of quantum mechanics allow for the distribution of a secret random key between two parties. Here we analyse the security of a protocol for establishing a common secret key…

Witnessing quantum capacities of correlated channels

Chiara Macchiavello, Massimiliano F. Sacchi

We test a general method to detect lower bounds of the quantum channel capacity for two-qubit correlated channels. We consider in particular correlated dephasing, depolarising and…

No-hypersignaling principle

Michele Dall'Arno, Sarah Brandsen, Alessandro Tosini +2

A paramount topic in quantum foundations, rooted in the study of the EPR paradox and Bell inequalities, is that of characterizing quantum theory in terms of the space-like correlat…

Quantum cellular automata and free quantum field theory

Giacomo M. D'Ariano, Paolo Perinotti

In a series of recent papers it has been shown how free quantum field theory can be derived without using mechanical primitives (including space-time, special relativity, quantizat…

Temperature of a single chaotic eigenstate

Fausto Borgonovi, Francesco Mattiotti, Felix M. Izrailev

The onset of thermalization in a closed finite system of randomly interacting bosons, at the level of a single eigenstate, is discussed. The main interest is in the emergence of th…

Detecting non-Markovianity of quantum evolution via spectra of dynamical maps

Dariusz Chruściński, Chiara Macchiavello, Sabrina Maniscalco

We provide an analysis on non-Markovian quantum evolution based on the spectral properties of dynamical maps. We introduce the dynamical analog of entanglement witness to detect no…

Dynamical Memory Effects in Correlated Quantum Channels

Carole Addis, Göktuğ Karpat, Chiara Macchiavello +1

Memory effects play a fundamental role in the study of the dynamics of open quantum systems. There exist two conceptually distinct notions of memory discussed for quantum channels…

Generation of energy-entangled W states via parametric fluorescence in integrated devices

M. Menotti, L. Maccone, J. E. Sipe +1

Tripartite entangled states, such as GHZ and W states, are typically generated by manipulating two pairs of polarization-entangled photons in bulk optics. Here we propose a scheme…

High-dimensional entanglement certification

Zixin Huang, Lorenzo Maccone, Akib Karim +3

Quantum entanglement is the ability of joint quantum systems to possess global properties (correlation among systems) even when subsystems have no definite individual property. Whi…

Entanglement-assisted quantum metrology

Zixin Huang, Chiara Macchiavello, Lorenzo Maccone

Entanglement-assisted quantum communication employs pre-shared entanglement between sender and receiver as a resource. We apply the same framework to quantum metrology, introducing…

Quantum walks with a one-dimensional coin

Alessandro Bisio, Giacomo Mauro D'Ariano, Marco Erba +2

Quantum walks (QWs) describe particles evolving coherently on a lattice. The internal degree of freedom corresponds to a Hilbert space, called coin system. We consider QWs on Cayle…

Discrete time Dirac quantum walk in 3+1 dimensions

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

In this paper we consider quantum walks whose evolution converges to the Dirac equation one in the limit of small wave-vectors. We show exact Fast Fourier implementation of the Dir…

Energy correlations of photon pairs generated by a silicon microring resonator probed by Stimulated Four Wave Mixing

Davide Grassani, Angelica Simbula, Stefano Pirotta +8

Compact silicon integrated devices, such as micro-ring resonators, have recently been demonstrated as efficient sources of quantum correlated photon pairs. The mass production of i…

Weyl, Dirac and Maxwell Quantum Cellular Automata: analitical solutions and phenomenological predictions of the Quantum Cellular Automata Theory of Free Fields

Alessandro Bisio, Giacomo Mauro D'Ariano, Paolo Perinotti +1

Recent advances on quantum foundations achieved the derivation of free quantum field theory from general principles, without referring to mechanical notions and relativistic invari…

Free quantum field theory from quantum cellular automata: derivation of Weyl, Dirac and Maxwell quantum cellular automata

Alessandro Bisio, Giacomo Mauro D'Ariano, Paolo Perinotti +1

After leading to a new axiomatic derivation of quantum theory, the new informational paradigm is entering the domain of quantum field theory, suggesting a quantum automata framewor…
