Detection methods to rule out completely co-positive and bi-entangling operations

C. Macchiavello, M. Rossi

In this work we extend the quantum channel detection method developed in [Phys. Rev. A 88, 042335 (2013)] and [Phys. Script. T153, 014044 (2013)] in order to detect other interesti…

Classical and quantum capacities of a fully correlated amplitude damping channel

A. D'Arrigo, G. Benenti, G. Falci +1

We study information transmission over a fully correlated amplitude damping channel acting on two qubits. We derive the single-shot classical channel capacity and show that entangl…

Noise robustness in the detection of non separable random unitary maps

C. Macchiavello, M. Rossi

We briefly review a recently proposed method to detect properties of quantum noise processes and quantum channels. We illustrate in detail the method for detecting non separable ra…

Doubly-Special Relativity from Quantum Cellular Automata

A. Bibeau-Delisle, A. Bisio, G. M. D'Ariano +2

It is shown how a Doubly-Special Relativity model can emerge from a quantum cellular automaton description of the evolution of countably many interacting quantum systems. We consid…

State estimation: direct state measurement vs. tomography

Lorenzo Maccone, Cosimo C. Rusconi

We compare direct state measurement (DST or weak state tomography) to conventional state reconstruction (tomography) through accurate Monte-Carlo simulations. We show that DST is s…

Time from quantum entanglement: an experimental illustration

Ekaterina Moreva, Giorgio Brida, Marco Gramegna +3

In the last years several theoretical papers discussed if time can be an emergent property deriving from quantum correlations. Here, to provide an insight into how this phenomenon…

Optimal processing of reversible quantum channels

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

We consider the general problem of the optimal transformation of N uses of (possibly different) unitary channels to a single use of another unitary channel in any finite dimension.…

Experimental Detection of Quantum Channels

Adeline Orieux, Linda Sansoni, Mauro Persechino +3

We demonstrate experimentally the possibility of efficiently detecting properties of quantum channels and quantum gates. The optimal detection scheme is first achieved for non enta…

A Quantum Biological Switch Based on Superradiance Transitions

D. Ferrari, G. L. Celardo, G. P. Berman +2

A linear chain of connected electron sites with two asymmetric sinks, one attached to each end, is used as a simple model of quantum electron transfer in photosynthetic bio-complex…

Fermionic computation is non-local tomographic and violates monogamy of entanglement

Giacomo Mauro D'Ariano, Franco Manessi, Paolo Perinotti +1

We show that the computational model based on local Fermionic modes in place of qubits does not satisfy local tomography and monogamy of entanglement, and has mixed states with max…

Efficient universal blind computation

Vittorio Giovannetti, Lorenzo Maccone, Tomoyuki Morimae +1

We give a cheat sensitive protocol for blind universal quantum computation that is efficient in terms of computational and communication resources: it allows one party to perform a…

Derivation of the Dirac Equation from Principles of Information Processing

G. M. D'Ariano, P. Perinotti

We show how the Dirac equation in three space-dimensions emerges from the large-scale dynamics of the minimal nontrivial quantum cellular automaton satisfying unitariety, locality,…

Identification of a reversible quantum gate: assessing the resources

Giulio Chiribella, Giacomo Mauro D'Ariano, Martin Roetteler

We assess the resources needed to identify a reversible quantum gate among a finite set of alternatives, including in our analysis both deterministic and probabilistic strategies.…

The Dirac Quantum Cellular Automaton in one dimension: Zitterbewegung and scattering from potential

Alessandro Bisio, Giacomo Mauro D'Ariano, Alessandro Tosini

We study the dynamical behaviour of the quantum cellular automaton of Refs. [1, 2], which reproduces the Dirac dynamics in the limit of small wavevectors and masses. We present ana…

Quantum metrology: why entanglement?

Lorenzo Maccone

We show why and when entanglement is needed for quantum-enhanced precision measurements, and which type of entanglement is useful. We give a simple, intuitive construction that sho…

Entanglement detection by Bragg scattering

Chiara Macchiavello, Giovanna Morigi

We show how to measure the structural witnesses proposed in [P. Krammer et al., Phys. Rev. Lett. 103, 100502 (2009)] for detecting entanglement in a spin chain using photon scatter…

Two-qubit non-Markovianity induced by a common environment

C. Addis, P. Haikka, S. McEndoo +2

We study non-Markovianity as backflow of information in two-qubit systems. We consider a setting where, by changing the distance between the qubits, one can interpolate between ind…

Determinism without causality

Giacomo M. D'Ariano, Franco Manessi, Paolo Perinotti

Causality has been often confused with the notion of determinism. It is mandatory to separate the two notions in view of the debate about quantum foundations. Quantum theory provid…
