Engineering of Chirped Apodized Sources for Quantum Spectroscopy
Linda Sansoni, Max Widarsson, Patrick Mutter +1
Quantum sources of light are of paramount importance for the development of photonic quantum technologies. The growing demand for bright, efficient, and spectrally engineered photo…
A Quantum Ghost Imaging Spectrometer
Andrea Chiuri, Federico Angelini, Simone Santoro +2
We present a device that exploits spatial and spectral correlations in parametric downconversion at once. By using a ghost imaging arrangement, we have been able to reconstruct rem…
Fast remote spectral discrimination through ghost spectrometry
Andrea Chiuri, Marco Barbieri, Iole Venditti +4
Assessing the presence of chemical, biological, radiological and nuclear threats is a crucial task which is usually dealt with by analyzing the presence of spectral features in a m…
Improved Tomographic Estimates by Specialised Neural Networks
Massimiliano Guarneri, Ilaria Gianani, Marco Barbieri +1
Characterization of quantum objects, being them states, processes, or measurements, complemented by previous knowledge about them is a valuable approach, especially as it leads to…
Tomographic characterisation of correlations in a photonic tripartite state
A. Chiuri, L. Mazzola, M. Paternostro +1
Starting from a four-partite photonic hyper-entangled Dicke resource, we report the full tomographic characterization of three-, two-, and one-qubit states obtained by projecting o…
Linear Optics Simulation of Non-Markovian Quantum Dynamics
Andrea Chiuri, Chiara Greganti, Laura Mazzola +2
The simulation of quantum processes is a key goal for the grand programme aiming at grounding quantum technologies as the way to explore complex phenomena that are inaccessible thr…
Experimental achievement of the entanglement assisted capacity for the depolarizing channel
Andrea Chiuri, Sandro Giacomini, Chiara Macchiavello +1
We experimentally demonstrate the achievement of the entanglement assisted capacity for classical information transmission over a depolarizing channel. The implementation is based…
Engineering a C-Phase quantum gate: optical design and experimental realization
Andrea Chiuri, Chiara Greganti, Paolo Mataloni
A two qubit quantum gate, namely the C-Phase, has been realized by exploiting the longitudinal momentum (i.e. the optical path) degree of freedom of a single photon. The experiment…
Experimental Quantum Networking Protocols via Four-Qubit Hyperentangled Dicke States
A. Chiuri, C. Greganti, M. Paternostro +2
We report the experimental demonstration of two quantum networking protocols, namely quantum 1->3 telecloning and open-destination teleportation, implemented using a four-qubit reg…
Experimental Realization of Optimal Noise Estimation for a General Pauli Channel
A. Chiuri, V. Rosati, G. Vallone +5
We present the experimental realization of the optimal estimation protocol for a Pauli noisy channel. The method is based on the generation of 2-qubit Bell states and the introduct…
Extremal Quantum Correlations: Experimental Study with Two-qubit States
Andrea Chiuri, Giuseppe Vallone, Mauro Paternostro +1
We explore experimentally the space of two-qubit quantum correlated mixed states, including frontier ones as defined by the use of quantum discord and von Neumann entropy. Our expe…
Fully nonlocal quantum correlations
Leandro Aolita, Rodrigo Gallego, Antonio Acín +4
Quantum mechanics is a nonlocal theory, but not as nonlocal as the no-signalling principle allows. However, there exist quantum correlations that exhibit maximal nonlocality: they…
Hyperentangled mixed phased Dicke states: optical design and detection
A. Chiuri, G. Vallone, N. Bruno +3
We present an experimental method to produce 4-qubit phased Dicke states, based on a source of 2-photon hyperentangled states. By introducing quantum noise in the multipartite syst…
