Experimentally determining the incompatibility of two qubit measurements
Andrea Smirne, Simone Cialdi, Daniele Cipriani +3
We describe and realize an experimental procedure for assessing the incompatibility of two qubit measurements. The experiment consists in a state discrimination task where either m…
Selective and tunable excitation of topological non-Hermitian skin modes
Stefano Longhi
Non-Hermitian lattices under semi-infinite boundary conditions sustain an extensive number of exponentially-localized states, dubbed non-Hermitian skin modes. Such states can be pr…
The decoherence-free subalgebra of Gaussian Quantum Markov Semigroups
Julián Agredo, Franco Fagnola, Damiano Poletti
We demonstrate a method for finding the decoherence-subalgebra of a Gaussian quantum Markov semigroup on the von Neumann algebra $\mathcal{B}(Γ(\mathbb{C…
Femtosecond laser micromachining for integrated quantum photonics
Giacomo Corrielli, Andrea Crespi, Roberto Osellame
Integrated quantum photonics, i.e. the generation, manipulation and detection of quantum states of light in integrated photonic chips, is revolutionizing the field of quantum infor…
Solving Rubik's Cube via Quantum Mechanics and Deep Reinforcement Learning
Sebastiano Corli, Lorenzo Moro, Davide E. Galli +1
Rubik's Cube is one of the most famous combinatorial puzzles involving nearly possible configurations. Its mathematical description is expressed by the Rubik's…
Non-Hermitian skin effect beyond the tight-binding models
Stefano Longhi
The energy bands of non-Hermitian systems exhibit nontrivial topological features that arise from the complex nature of the energy spectrum. Under periodic boundary conditions (PBC…
Quantum guessing games with posterior information
Claudio Carmeli, Teiko Heinosaari, Alessandro Toigo
Quantum guessing games form a versatile framework for studying different tasks of information processing. A quantum guessing game with posterior information uses quantum systems to…
A greedy reconstruction algorithm for the identification of spin distribution
S. Buchwald, G. Ciaramella, J. Salomon +1
We propose a greedy reconstruction algorithm to find the probability distribution of a parameter characterizing an inhomogeneous spin ensemble in Nuclear Magnetic Resonace. The ide…
Reconfigurable continuously-coupled 3D photonic circuit for Boson Sampling experiments
Francesco Hoch, Simone Piacentini, Taira Giordani +10
Boson Sampling is a computational paradigm representing one of the most viable and pursued approaches to demonstrate the regime of quantum advantage. Recent results have demonstrat…
Quantum spatial search in two-dimensional waveguide arrays
C. Benedetti, D. Tamascelli, M. G. A. Paris +1
Continuous-time quantum walks (CTQW) have shown the capability to perform efficiently the spatial search of a marked site on many kinds of graphs. However, most of such graphs are…
Non-Hermitian Maryland Model
Stefano Longhi
Non-Hermitian systems with aperiodic order display phase transitions that are beyond the paradigm of Hermitian physics. Unfortunately, owing to the incommensurability of the potent…
Quantum Compiling by Deep Reinforcement Learning
Lorenzo Moro, Matteo G. A. Paris, Marcello Restelli +1
The architecture of circuital quantum computers requires computing layers devoted to compiling high-level quantum algorithms into lower-level circuits of quantum gates. The general…
A quantum-enhanced wide-field phase imager
Robin Camphausen, Álvaro Cuevas, Luc Duempelmann +7
Quantum techniques can be used to enhance the signal-to-noise ratio in optical imaging. Leveraging the latest advances in single photon avalanche diode array cameras and multi-phot…
Experimental quantum memristor
Michele Spagnolo, Joshua Morris, Simone Piacentini +6
Quantum computer technology harnesses the features of quantum physics for revolutionizing information processing and computing. As such, quantum computers use physical quantum gate…
A note on "Algebraic approach to Casimir force between two -like potentials" (K. Ziemian, Ann. Henri Poincaré, Online First, 2021)
Davide Fermi, Livio Pizzocchero
We comment on the recent work [1], and on its relations with our papers [2,3] cited therein. In particular we show that, contrarily to what stated in [1], the Casimir energy densit…
Quantum algorithms for SVD-based data representation and analysis
Armando Bellante, Alessandro Luongo, Stefano Zanero
This paper narrows the gap between previous literature on quantum linear algebra and practical data analysis on a quantum computer, formalizing quantum procedures that speed-up the…
Experimental statistical signature of many-body quantum interference
Taira Giordani, Fulvio Flamini, Matteo Pompili +8
Multi-particle interference is an essential ingredient for fundamental quantum mechanics phenomena and for quantum information processing to provide a computational advantage, as r…
Protective Measurement -- a new quantum measurement paradigm: detailed description of the first realisation
Enrico Rebufello, Fabrizio Piacentini, Alessio Avella +9
We present a detailed description of the experiment realising for the first time a protective measurement, a novel measurement protocol which combines weak interactions with a ``pr…
Quantum optomechanical system in a Mach-Zehnder interferometer
Alberto Barchielli, Matteo Gregoratti
We consider an oscillating micromirror replacing one of the two fixed mirrors of a Mach-Zehnder interferometer. In this ideal optical set-up the quantum oscillator is subjected to…
