Quantum implementation of an artificial feed-forward neural network

Francesco Tacchino, Panagiotis Barkoutsos, Chiara Macchiavello +3

Artificial intelligence algorithms largely build on multi-layered neural networks. Coping with their increasing complexity and memory requirements calls for a paradigmatic change i…

Scattering and perturbation theory for discrete-time dynamics

Alessandro Bisio, Nicola Mosco, Paolo Perinotti

We present a systematic treatment of scattering processes for quantum systems whose time evolution is discrete. We define and show some general properties of the scattering operato…

Protecting quantum coherences from static noise and disorder

Chahan M. Kropf

Quantum coherences are paramount resources for applications, such as quantum-enhanced light-harvesting or quantum computing, which are fragile against environmental noise. We here…

Cellular automata in operational probabilistic theories

Paolo Perinotti

The theory of cellular automata in operational probabilistic theories is developed. We start introducing the composition of infinitely many elementary systems, and then use this no…

Electric-field assisted optimal quantum transport of photo-excitations in polar heterostructures

Chahan M. Kropf, G. Luca Celardo, Claudio Giannetti +1

Transition-metal-oxide (TMO) heterostructures are promising candidates for building photon-harvesting devices which can exploit optimal quantum transport of charge excitations gene…

Classical theories with entanglement

Giacomo Mauro D'Ariano, Marco Erba, Paolo Perinotti

We investigate operational probabilistic theories where the pure states of every system are the vertices of a simplex. A special case of such theories is that of classical theories…

Efficient accessible bounds to the classical capacity of quantum channels

Chiara Macchiavello, Massimiliano F. Sacchi

We present a method to detect lower bounds to the classical capacity of quantum communication channels by means of few local measurements (i.e. without complete process tomography)…

Information and disturbance in operational probabilistic theories

Giacomo Mauro D'Ariano, Paolo Perinotti, Alessandro Tosini

Any measurement is intended to provide information on a system, namely knowledge about its state. However, we learn from quantum theory that it is generally impossible to extract i…

Quantum radar

Lorenzo Maccone, Changliang Ren

We propose a quantum metrology protocol for the localization of a non-cooperative point-like target in three-dimensional space, by illuminating it with electromagnetic waves. It em…

Knowledge of Quantum Hidden Variables Enables Backwards-In-Time Signaling

Avishy Carmi, Eliahu Cohen, Lorenzo Maccone +1

Bell's theorem implies that any completion of quantum mechanics which uses hidden variables (that is, preexisting values of all observables) must be nonlocal in the Einstein sense.…

Chirality from quantum walks without quantum coin

Giacomo Mauro D'Ariano, Marco Erba, Paolo Perinotti

Quantum walks (QWs) describe the evolution of quantum systems on graphs. An intrinsic degree of freedom---called the coin and represented by a finite-dimensional Hilbert space---is…

Optimal entanglement witnesses from limited local measurements

Alberto Riccardi, Dariusz Chruściński, Chiara Macchiavello

We address the problem of optimising entanglement witnesses when a limited fixed set of local measurements can be performed on a bipartite system, thus providing a procedure, feasi…

Squeezing metrology: a unified framework

Lorenzo Maccone, Alberto Riccardi

Quantum metrology theory has up to now focused on the resolution gains obtainable thanks to the entanglement among N probes. Typically, a quadratic gain in resolution is achievable…
