Data-Driven Inference, Reconstruction, and Observational Completeness of Quantum Devices
Michele Dall'Arno, Francesco Buscemi, Alessandro Bisio +1
The range of a quantum measurement is the set of outcome probability distributions that can be produced by varying the input state. We introduce data-driven inference as a protocol…
Towards high-temperature coherence-enhanced transport in few-atomic layers heterostructures
Chahan M. Kropf, Angelo Valli, Paolo Franceschini +4
The possibility to exploit quantum coherence to strongly enhance the efficiency of charge transport in solid state devices working at ambient conditions would pave the way to disru…
Preserving Measurements for Optimal State Discrimination over Quantum Channels
Spiros Kechrimparis, Tanmay Singal, Chahan M. Kropf +1
In this work, we consider optimal state discrimination for a quantum system that interacts with an environment, i.e., states evolve under a quantum channel. We show the conditions…
An Artificial Neuron Implemented on an Actual Quantum Processor
Francesco Tacchino, Chiara Macchiavello, Dario Gerace +1
Artificial neural networks are the heart of machine learning algorithms and artificial intelligence protocols. Historically, the simplest implementation of an artificial neuron tra…
Ancilla-assisted schemes are beneficial for Gaussian state phase estimation
Zixin Huang, Chiara Macchiavello, Lorenzo Maccone +1
We study interferometry with Gaussian states and show that an ancilla-assisted scheme outperforms coherent state interferometry for all levels of loss. We also compare the ancilla-…
State independent uncertainty relations from eigenvalue minimization
Paolo Giorda, Lorenzo Maccone, Alberto Riccardi
We consider uncertainty relations that give lower bounds to the sum of variances. Finding such lower bounds is typically complicated, and efficient procedures are known only for a…
Quantum measurements of time
Lorenzo Maccone, Krzysztof Sacha
We propose a time-of-arrival operator in quantum mechanics by conditioning on a quantum clock. This allows us to bypass some of the problems of previous proposals, and to obtain a…
Optimal probabilistic storage and retrieval of unitary channels
Michal Sedlák, Alessandro Bisio, Mário Ziman
We address the question of a quantum memory storage of quantum dynamics. In particular, we design an optimal protocol for probabilistic storage-and-retrieval of unitary ch…
Scalar fermionic cellular automata on finite Cayley graphs
Paolo Perinotti, Leopoldo Poggiali
A map on finitely many fermionic modes represents a unitary evolution if and only if it preserves canonical anti-commutation relations. We use this condition for the classification…
A fundamental problem in quantizing general relativity
Lorenzo Maccone
We point out a fundamental problem that hinders the quantization of general relativity: quantum mechanics is formulated in terms of systems, typically limited in space but infinite…
Symmetries of the Dirac quantum walk and emergence of the de Sitter group
Luca Apadula, Alessandro Bisio, Giacomo Mauro D'Ariano +1
A quantum walk describes the discrete unitary evolution of a quantum particle on a discrete graph. Some quantum walks, referred to as the Weyl and Dirac quantum walks, provide a de…
Introduction to the book "Quantum Theory: Informational Foundations and Foils"
Giulio Chiribella, Robert W. Spekkens
We present here our introduction to the contributed volume "Quantum Theory: Informational Foundations and Foils", Springer Netherlands (2016). It highlights recent trends in quantu…
Causality re-established
Giacomo Mauro D'Ariano
Causality never gained the status of a "law" or "principle" in physics. Some recent literature even popularized the false idea that causality is a notion that should be banned from…
Solutions of a two-particle interacting quantum walk
Alessandro Bisio, Giacomo Mauro D'Ariano, Nicola Mosco +2
We study the solutions of the interacting Fermionic cellular automaton introduced in Ref. [Phys Rev A 97, 032132 (2018)]. The automaton is the analogue of the Thirring model with b…
State-independent preparation uncertainty relations
Hubert de Guise, Lorenzo Maccone, Barry C. Sanders +1
The standard state-dependent Heisenberg-Robertson uncertainly-relation lower bound fails to capture the quintessential incompatibility of observables as the bound can be zero for s…
Noise-dependent optimal strategies for quantum metrology
Zixin Huang, Chiara Macchiavello, Lorenzo Maccone
We show that for some noisy channels, the optimal entanglement-assisted strategy depends on the noise level. We note that there is a non-trivial crossover between the parallel-enta…
The solution of the Sixth Hilbert Problem: the Ultimate Galilean Revolution
Giacomo Mauro D'Ariano
I argue for a full mathematisation of the physical theory, including its axioms, which must contain no physical primitives. In provocative words: "physics from no physics". Althoug…
