Direct high-resolution characterization of quantum correlations via classical measurements
Andreas Eckstein, Guillaume Boucher, Aristide Lemaître +6
Quantum optics plays a central role in the study of fundamental concepts in quantum mechanics, and in the development of new technological applications. Typical experiments employ…
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…
Cooperativity of a few quantum emitters in a single-mode cavity
Eduardo Mascarenhas, Dario Gerace, Marcelo França Santos +1
We theoretically investigate the emission properties of a single-mode cavity coupled to a mesoscopic number of incoherently pumped quantum emitters. We propose an operational measu…
Quantum-Information Processing with Hybrid Spin-Photon Qubit Encoding
S. Carretta, A. Chiesa, F. Troiani +3
We introduce a scheme to perform quantum-information processing that is based on a hybrid spin-photon qubit encoding. The proposed qubits consist of spin-ensembles coherently coupl…
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…
A quantum optical valve in a nonlinear-linear resonator junction
Eduardo Mascarenhas, Daniel Valente, Simone Montangero +3
Electronic diodes, which enable the rectification of an electrical energy flux, have played a crucial role in the development of current microelectronics after the invention of sem…
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…
A review on super dense coding over covariant noisy channels
Zahra Shadman, Hermann Kampermann, Chiara Macchiavello +1
We study the performance of the super dense coding protocol in the presence of quantum channels with covariant noise. We first consider the bipartite case and review in a unified w…
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…
Hamiltonian dynamics of a quantum of space: hidden symmetries and spectrum of the volume operator, and discrete orthogonal polynomials
Vincenzo Aquilanti, Dimitri Marinelli, Annalisa Marzuoli
The action of the quantum mechanical volume operator, introduced in connection with a symmetric representation of the three-body problem and recently recognized to play a fundament…
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…
