Programmable frequency-bin quantum states in a nano-engineered silicon device
Marco Clementi, Federico A. Sabattoli, Massimo Borghi +12
Photonic qubits should be controllable on-chip and noise-tolerant when transmitted over optical networks for practical applications. Furthermore, qubit sources should be programmab…
Unifying different notions of quantum incompatibility into a strict hierarchy of resource theories of communication
Francesco Buscemi, Kodai Kobayashi, Shintaro Minagawa +2
While there is general consensus on the definition of incompatible POVMs, moving up to the level of instruments one finds a much less clear situation, with mathematically different…
Construction of efficient Schmidt number witnesses for high-dimensional quantum states
Nikolai Wyderka, Giovanni Chesi, Hermann Kampermann +2
Recent progress in quantum optics has led to setups that are able to prepare high-dimensional quantum states for quantum information processing tasks. As such, it is of importance…
Schroedinger cats and quantum complementarity
Lorenzo Maccone
Complementarity tells us we cannot know precisely the values of all the properties of a quantum object at the same time: the precise determination of one property implies that the…
Super spontaneous four-wave mixing in an array of silicon microresonators
Massimo Borghi, Federico Andrea Sabattoli, Houssein El Dirani +9
Composite optical systems can show compelling collective dynamics. For instance, the cooperative decay of quantum emitters into a common radiation mode can lead to superradiance, w…
Quantum metrology of noisy spreading channels
Wojciech Górecki, Alberto Riccardi, Lorenzo Maccone
We provide the optimal measurement strategy for a class of noisy channels that reduce to the identity channel for a specific value of a parameter (spreading channels). We provide a…
Probing coherent quantum thermodynamics using a trapped ion
O. Onishchenko, G. Guarnieri, P. Rosillo-Rodes +6
Quantum thermodynamics is aimed at grasping thermodynamic laws as they apply to thermal machines operating in the deep quantum regime, a regime in which coherences and entanglement…
Error-analysis for the Sorkin and Peres tests performed on a quantum computer
Simanraj Sadana, Lorenzo Maccone, Urbasi Sinha
We use quantum computers to test the foundations of quantum mechanics through quantum algorithms that implement some of the experimental tests as the basis of the theory's postulat…
Tight bounds from multiple-observable entropic uncertainty relations
Alberto Riccardi, Giovanni Chesi, Chiara Macchiavello +1
We investigate the additivity properties for both bipartite and multipartite systems by using entropic uncertainty relations (EUR) defined in terms of the joint Shannon entropy of…
Multiqubit noise deconvolution and characterization
Simone Roncallo, Lorenzo Maccone, Chiara Macchiavello
We present a noise deconvolution technique for obtaining noiseless expectation values of noisy observables at the output of multiqubit quantum channels. For any number of qubits or…
Geometric Event-Based Relativistic Quantum Mechanics
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone
We propose a special relativistic framework for quantum mechanics. It is based on introducing a Hilbert space for events. Events are taken as primitive notions (as customary in rel…
Entanglement entropy production in Quantum Neural Networks
Marco Ballarin, Stefano Mangini, Simone Montangero +2
Quantum Neural Networks (QNN) are considered a candidate for achieving quantum advantage in the Noisy Intermediate Scale Quantum computer (NISQ) era. Several QNN architectures have…
Multipartite entanglement in qudit hypergraph states
Daniele Malpetti, Alfredo Bellisario, Chiara Macchiavello
We study entanglement properties of hypergraph states in arbitrary finite dimension. We compute multipartite entanglement of elementary qudit hypergraph states, namely those endowe…
Quantum neural network autoencoder and classifier applied to an industrial case study
Stefano Mangini, Alessia Marruzzo, Marco Piantanida +3
Quantum computing technologies are in the process of moving from academic research to real industrial applications, with the first hints of quantum advantage demonstrated in recent…
When does a particle arrive?
Simone Roncallo, Krzysztof Sacha, Lorenzo Maccone
We compare the proposals that have appeared in the literature to describe a measurement of the time of arrival of a quantum particle at a detector. We show that there are multiple…
Incompatibility of observables, channels and instruments in information theories
Giacomo M. D'Ariano, Paolo Perinotti, Alessandro Tosini
Every theory of information, including classical and quantum, can be studied in the framework of operational probabilistic theories--where the notion of test generalizes that of qu…
Quantum epistemology and falsification of random generators
Giacomo Mauro D'Ariano
The operational axiomatization of quantum theory can be regarded as a set of six epistemological rules for falsifying propositions of the theory. In particular, the Purification po…
No-signalling constrains quantum computation with indefinite causal structure
Luca Apadula, Alessandro Bisio, Paolo Perinotti
Quantum processes with indefinite causal structure emerge when we wonder which are the most general evolutions, allowed by quantum theory, of a set of local systems which are not a…
Qubit noise deconvolution
Stefano Mangini, Lorenzo Maccone, Chiara Macchiavello
We present a noise deconvolution technique to remove a wide class of noises when performing arbitrary measurements on qubit systems. In particular, we derive the inverse map of the…
