All-optical quantum simulator of qubit noisy channels
Simone Cialdi, Matteo A. C. Rossi, Claudia Benedetti +4
We suggest and demonstrate an all-optical quantum simulator for single-qubit noisy channels originating from the interaction with a fluctuating field. The simulator employs the pol…
Quantum Critical Scaling under Periodic Driving
Salvatore Lorenzo, Jamir Marino, Francesco Plastina +2
Universality is key to the theory of phase transition stating that the equilibrium properties of observables near a phase transition can be classified according to few critical exp…
Generalized master equations leading to completely positive dynamics
Bassano Vacchini
We provide a general construction of quantum generalized master equations with memory kernel leading to well defined, that is completely positive and trace preserving, time evoluti…
Probing quantum state space: does one have to learn everything to learn something?
Claudio Carmeli, Teiko Heinosaari, Jussi Schultz +1
Determining the state of a quantum system is a consuming procedure. For this reason, whenever one is interested only in some particular property of a state, it would be desirable t…
Noisy quantum walks of two indistinguishable interacting particles
Ilaria Siloi, Claudia Benedetti, Enrico Piccinini +4
We investigate the dynamics of continuous-time two-particle quantum walks on a one-dimensional noisy lattice. Depending on the initial condition, we show how the interplay between…
Trade-off between speed and cost in shortcuts to adiabaticity
Steve Campbell, Sebastian Deffner
Achieving effectively adiabatic dynamics is a ubiquitous goal in almost all areas of quantum physics. Here, we study the speed with which a quantum system can be driven when employ…
Quantum non-Markovianity induced by Anderson localization
Salvatore Lorenzo, Federico Lombardo, Francesco Ciccarello +1
As discovered by P. W. Anderson, excitations do not propagate freely in a disordered lattice, but, due to destructive interference, they localise. As a consequence when an atom int…
High-order dispersion effects in two-photon interference
Z. Mazzotta, S. Cialdi, D. Cipriani +2
Two-photon interference and Hong-Ou-Mandel (HOM) effect are relevant tools for quantum metrology and quantum information processing. In optical coherence tomography, HOM effect is…
Energy backflow in strongly coupled non-Markovian continuous-variables systems
Giacomo Guarnieri, Johannes Nokkala, Rebecca Schmidt +2
By employing the full counting statistics formalism, we characterize the first moment of energy that is exchanged during a generally non-Markovian evolution in non-driven continuou…
Characterization of qubit chains by Feynman probes
D. Tamascelli, C. Benedetti, S. Olivares +1
We address the characterization of qubit chains and assess the performances of local measurements compared to those provided by Feynman probes, i.e. nonlocal measurements realized…
Probing deformed quantum commutators
Matteo A. C. Rossi, Tommaso Giani, Matteo G. A. Paris
Quantum gravity theories predict a minimal length at the order of magnitude of the Planck length, under which the concepts of space and time lose every physical meaning. In quantum…
Quantum-limited estimation of continuous spontaneous localization
Sam McMillen, Matteo Brunelli, Matteo Carlesso +4
We apply the formalism of quantum estimation theory to extract information about potential collapse mechanisms of the continuous spontaneous localisation (CSL) form. In order to es…
Decoherence and noise in open quantum system dynamics
Bassano Vacchini
We consider the description of quantum noise within the framework of the standard Copenhagen interpretation of quantum mechanics applied to a composite system environment setting.…
Quantum incompatibility in collective measurements
Claudio Carmeli, Teiko Heinosaari, Daniel Reitzner +2
We study the compatibility (or joint measurability) of quantum observables in a setting where the experimenter has access to multiple copies of a given quantum system, rather than…
Reduced dynamical maps in the presence of initial correlations
Bassano Vacchini, Giulio Amato
We introduce a general framework for the construction of completely positive dynamical evolutions in the presence of system-environment initial correlations. The construction relie…
Reconstruction of electromagnetic field states by a probe qubit
Fabrizio Angaroni, Giuliano Benenti, Giuliano Strini
We propose a method to measure the quantum state of a single mode of the electromagnetic field. The method is based on the interaction of the field with a probe qubit. The qubit po…
Quantum backflow effect and nonclassicality
Francesco Albarelli, Tommaso Guaita, Matteo G. A. Paris
The quantum backflow effect is a counterintuitive behavior of the probability current of a free particle, which may be negative even for states with vanishing negative momentum com…
Efficient Pure State Quantum Tomography from Five Orthonormal Bases
Claudio Carmeli, Teiko Heinosaari, Michael Kech +2
For any finite dimensional Hilbert space, we construct explicitly five orthonormal bases such that the corresponding measurements allow for efficient tomography of an arbitrary pur…
Probing the diamagnetic term in light-matter interaction
Matteo A. C. Rossi, Matteo Bina, Matteo G. A. Paris +3
We address the quantum estimation of the diamagnetic, or , term in an effective model of light-matter interaction featuring two coupled oscillators. First, we calculate the qu…
Assessing the significance of fidelity as a figure of merit in quantum state reconstruction of discrete and continuous variable systems
Antonio Mandarino, Matteo Bina, Carmen Porto +3
We experimentally address the significance of fidelity as a figure of merit in quantum state reconstruction of discrete (DV) and continuous variable (CV) quantum optical systems. I…
Asymmetric Talbot-Lau interferometry for inertial sensing
Simone Sala, Marco Giammarchi, Stefano Olivares
We study in detail a peculiar configuration of the Talbot-Lau matter wave interferometer, characterised by unequal distances between the two diffraction gratings and the observatio…
Dicke coupling by feasible local measurements at the superradiant quantum phase transition
M. Bina, I. Amelio, M. G. A. Paris
We address characterization of many-body superradiant systems and establish a fundamental connection between quantum criticality and the possibility of locally estimating the coupl…
